Rare Celestial Solar Halo Graces China's Northernmost Village | Earth Science

Rare Celestial Solar Halo Graces China's Northernmost Village | Earth Science

In the crystalline air of China's northernmost edge, where darkness claims 17 hours of each winter day, an extraordinary natural phenomenon has virtually transformed the sky into a canvas of ethereal beauty.

Beiji Village in Heilongjiang province's Mohe City, aptly named "China's North Pole," has become nature's theater for a rare double feature: a magnificent sun halo dancing in partnership with diamond dust.

Solar halos are generally created by randomly oriented ice crystals in thin, high cirrus clouds. Circular 22 degree halos like this one are visible much more often than rainbows.

Against the pristine arctic blue sky, a perfect ring of light encircles the winter sun like a celestial crown. Below, stretching toward the snow-blanketed earth, a brilliant white pillar of light pierces the frigid air, while rainbow-hued parhelia—commonly known as sundogs—shimmer on either side, creating nature's own abstract masterpiece.

Sundogs are one of the most common types of ice halo. They occur when light rays enter the side of an ice crystal and leave through another side inclined about 60 degrees to the first. Sundogs are most easily seen when the Sun is low in the sky; the halos occurring on either side of it at about 22 degrees. The part of a sundog closest to the Sun always forms a layer of red, while greens and blues form beyond that. Sundogs are visible all over the world and at any time of year, regardless of the temperature at the surface.

This rare convergence of optical phenomena arrives just as Beiji Village braces for the Dongzhi, the traditional Chinese winter solstice festival which falls on Saturday this year.

With the opening event featuring "boiling water instantly turning to ice in mid-air" amid the freezing temperatures, the Mohe Dongzhi Festival is now underway. Thousands of locals and tourists have gathered in the village to celebrate the annual festivities.

The celebration blends traditional customs, such as drinking lamb soup and eating dumplings, with lively performances and modern ice and snow attractions. The brief seven hours of daylight make such displays all the more precious.

As winter tourism continues to flourish in northern China, Beiji Village has become an increasingly popular destination for travelers.

Winter Solstice, also known as "Dongzhi" in Chinese, is the 22nd of the 24 Solar Terms on the Chinese lunar calendar. It has the shortest day and longest night of the year.

On this day, the sun shines directly on the Tropic of Capricorn, making the short daylight and long nights particularly noticeable for people living in the Northern Hemisphere.

NASA’s Goldstone Deep Space Network Welcomes New 34-Meter Antenna | JPL

NASA’s Goldstone Deep Space Network Welcomes New 34-Meter Antenna | JPL

A time-lapse video of construction operations for a new antenna at the NASA Deep Space Network’s Goldstone Space Communications Complex near Barstow, California, on Dec. 18, 2024. 

Called Deep Space Station 23 (DSS-23), the new antenna joins others at three Deep Space Network complexes around the world that communicate with spacecraft at the Moon and beyond. During construction operations on Dec. 18, the 112-foot-wide (34-meter-wide) steel parabolic reflector framework was lowered into position by crane before a crew bolted it into place. Shortly after, engineers placed what’s called a quadripod onto the center of the dish framework. A four-legged support structure, the quadripod weighs 16 ½ tons and features a curved subreflector that will direct radio frequency signals from deep space to bounce off the main reflector into the antenna’s pedestal, where the antenna’s receiver is housed. 

DSS-23 is a multi-frequency beam waveguide antenna that will boost the DSN’s capacity and enhance NASA’s deep space communications capabilities for decades to come. Once online in 2026, DSS-23 will be the fifth of six new beam waveguide antennas to be added to the network, following DSS-53 that was added at the DSN’s Madrid complex in 2022. 

The DSN allows missions to track, send commands to, and receive scientific data from faraway spacecraft. It is managed by NASA’s Jet Propulsion Laboratory in Southern California for the agency’s Space Communications and Navigation (SCaN) program, which is located at NASA Headquarters within the Space Operations Mission Directorate.

Northern Lights from Kitt Peak, Arizona

Northern Lights from Kitt Peak, Arizona

The aurora borealis, also known as the northern lights, as seen from Kitt Peak National Observatory in Arizona, USA. Auroras occur in an upper layer of Earth’s atmosphere called the ionosphere, but they typically originate with activity on the Sun. Occasionally, during explosions called coronal mass ejections, the Sun releases charged particles that speed across the solar system. 

Auroras are produced when the Earth's magnetosphere is sufficiently disturbed by the solar wind that the trajectories of charged particles in solar wind and magnetospheric plasma, mainly in the form of electrons and protons, precipitate them into the upper atmosphere (thermosphere/exosphere) due to Earth's magnetic field, where their energy is lost. The resulting ionization and excitation of atmospheric constituents emits light of varying color and complexity. [Wikipedia]

Solid Colored Aurora

Green is common at the upper latitudes, while red is rare. On the other hand, aurora viewed from lower latitudes tend to be red.

Element Emission Colors

Oxygen: The big player in the aurora is oxygen. Oxygen is responsible for the vivid green (wavelength of 557.7 nm) and also for a deep brownish-red (wavelength of 630.0 nm). Pure green and greenish-yellow aurorae result from the excitation of oxygen.

Nitrogen: Nitrogen emits blue (multiple wavelengths) and red light.

Other Gases: Other gases in the atmosphere become excited and emit light, although the wavelengths may be outside of the range of human vision or else too faint to see. Hydrogen and helium, for example, emit blue and purple. Although our eyes cannot see all of these colors, photographic film and digital cameras often record a broader range of hues.

Aurora Colors According to Altitude

Above 150 miles: red, oxygen

Up to 150 miles: green, oxygen

Above 60 miles: purple or violet, nitrogen

Up to 60 miles: blue, nitrogen

NASA Mars Report: New Year/New Mars | Martian Spring Activity Begins | JPL

NASA Mars Report: New Year/New Mars | Martian Spring Activity Begins | JPL

Planetary scientists have recently marked a new year on Mars, a milestone that occurs every 687 days. Because the Martian new year coincides with spring in the planet’s northern hemisphere, it is a period of high activity, including avalanches and exploding jets of gas. JPL research scientist Serina Diniega explains changes to the Martian surface that scientists can track with spacecraft like NASA’s Mars Reconnaissance Orbiter (MRO).

Circling Mars since 2006, MRO carries a suite of science instruments that collect data on the planet’s surface and atmosphere. Among them is the High Resolution Imaging Science Experiment (HiRISE) camera. It captured many of the detailed views seen here.

Mars Reconnaissance Orbiter (MRO) is a spacecraft designed to study the geology and climate of Mars, to provide reconnaissance of future landing sites, and to relay data from surface missions back to Earth. It was launched on August 12, 2005, and reached Mars on March 10, 2006. 

For more information on NASA’s Mars Reconnaissance Orbiter mission, visit: 
science.nasa.gov/mission/mars-reconnaissance-orbiter

The Jet Propulsion Laboratory (JPL) manages MRO for NASA’s Science Mission Directorate in Washington. Caltech, in Pasadena, manages JPL for NASA. The University of Arizona, in Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., in Boulder, Colorado. The Context Camera was built by, and is operated by, Malin Space Science Systems in San Diego.

What are Gamma-ray Bursts? | NASA Goddard

What are Gamma-ray Bursts? | NASA Goddard

Gamma-ray bursts (GRBs) are the most powerful explosions in the cosmos. They first came to the attention of astronomers in the 1970s when new satellites detected this surprising phenomenon. Over decades, scientists have found that these blasts could be detected in the sky almost every day, and that they were both extremely distant. The closest known GRB was over 100 million light-years away—and enormously powerful. Gamma-ray bursts are now linked to the explosive deaths of massive stars and to mergers of compact objects, like neutron stars and black holes. However, many puzzles remain.

NASA's "Space to Ground": Year 2024 in Review | International Space Station

The Year 2024 on the International Space Station was filled with excitement, challenges, and milestones as we marked 25 unbroken years of humans living, working, and flying in one of humanity's homes in low-earth orbit.

Update: Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner of Russia concluded their spacewalk on December 19, 2024, at 5:53 p.m. EST after seven hours and 17 minutes. Ovchinin and Vagner completed all of their major objectives, which included installing an experiment package designed to monitor celestial x-ray sources and new electrical connector patch panels and removing several experiments for disposal. The two cosmonauts were unable to complete their non-critical final objective due to time constraints. This  was to relocate a control panel for the European robotic arm, attached to the Nauka multipurpose laboratory module.

This was the second spacewalk in Ovinchin’s career, and the first for Vagner. It is the 272nd spacewalk for space station assembly, maintenance, and upgrades.

Saturn - April 25, 2008

Planet Saturn's rings can appear similar to the grooves of a vinyl record. The first 12-inch, 33-revolutions per minute (RPM) record was produced by the American company Columbia Broadcasting System (CBS) in 1948. Twelve-inch albums could hold an album’s worth of songs on each side. They arrived on the market when the postwar entertainment industry was booming. Consumers were ready to buy these 12-inch LP (long-play) records. They quickly became the industry standard. Instead of the hard shellac that 78s were made from, 12-inch LPs consisted of polyvinyl carbonate, the material that gives vinyl records their name.

NASA's Cassini spacecraft arrived in the Saturn system in 2004 and ended its mission in 2017 by deliberately plunging into Saturn's atmosphere. This method was chosen because it is necessary to ensure protection and prevent biological contamination to any of the moons of Saturn thought to offer potential habitability.

The Cassini-Huygens mission was a cooperative project of NASA, European Space Agency (ESA) and the Italian Space Agency. NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the mission for NASA's Science Mission Directorate, Washington. JPL designed, developed and assembled the Cassini orbiter. The Cassini radar instrument was built by JPL and the Italian Space Agency, working with team members from the U.S. and several European countries.

Planet Mars: 'Texoli' Butte on Mount Sharp | NASA Curiosity Mars Rover

Support FriendsofNASA.org

Celebrating 12+ Years on Mars (2012-2024)
Mission Name: Mars Science Laboratory (MSL)
Rover Name: Curiosity
Main Job: To determine if Mars was ever habitable to microbial life. 
Launch: Nov. 6, 2011
Landing Date: Aug. 5, 2012, Gale Crater, Mars

For more information on NASA's Mars missions, visit: mars.nasa.gov

NASA's Curiosity Mars rover used its right Mast Camera, or Mastcam, to capture this panorama on Nov. 26, 2024, the 4,375th Martian day, or sol, of the mission. Made from 251 individual images containing 393 million pixels, the panorama's color has been adjusted to match lighting conditions as the human eye would see them on Earth. This is one of the largest high-resolution panoramas Curiosity has taken during its mission.

Curiosity is making its way up the foothills of Mount Sharp, a 3-mile-tall (5-kilometer-tall) mountain found within Mars' Gale Crater. Dominating the scene in this image is a butte on Mount Sharp nicknamed "Texoli". It has many stratigraphic layers that scientists can study to learn more about the formation of this region of Mars. Texoli stands about 525 feet (160 meters) tall.

A butte is "an isolated hill with steep, often vertical sides and a small, relatively flat top."

To the right of Texoli is another butte nicknamed "Wilkerson." It is 262 feet (80 meters) tall. Curiosity will travel between the two buttes as it drives away from Gediz Vallis channel. It has been investigating this area for the past year, and from Gediz Vallis (Gediz valley) itself, where it has been for four years.

On the horizon beyond Texoli on the left side of the image is the Yardang Unit—a higher-elevation geologic region that Curiosity's scientists hope to visit in the years to come. On the horizon on the right side of the image, beyond Wilkerson, is the floor of Gale Crater and, visible through a dusty haze, the crater's distant northern rim.

Cosmic Jingles: "Listen" to Euclid Space Telescope’s Image of Nebula M78 in Orion

Cosmic Jingles: "Listen" to Euclid Space Telescope’s Image of Nebula M78 in Orion

An ethereal dance of misty clouds of interstellar dust with a myriad of distant stars and galaxies speckled like paint drops over a black canvas. This is a sonification of a breathtaking image taken by the European Space Agency's Euclid space telescope of the young star-forming region Messier 78. 

The sonification offers a unique representation of the data collected by Euclid. It lets us explore the stellar nurseries in M78 through sound. Close your eyes and listen to let the cosmic image be drawn by your mind’s eye, or watch as the traceback line in this video follows the sounds to color the image from left to right.  

The twinkling sounds of pitches and volumes represent the galaxies and stars in the frame. The pitch of the sound points towards where we see the dot of light in the image. Higher pitches tell us that a star or galaxy appears further at the top in the image along the traceback line.  

The brightness of these objects in and around M78 are represented by the volume of the twinkles. Whenever we hear a particularly loud clink, the star or galaxy that Euclid observed appears particularly bright in the image. 

Underlying these jingling sounds, we can hear a steady undertone, made up of two chords which represent regions in Messier 78. This sound intensifies as the traceback line approaches first the brightest, and later the densest regions in the nebula.  

The first two deeper crescendos in this undertone indicate two patches in the image where the most intense color is blue/purple. These appear as two ‘cavities’ in M78, where newly forming stars carve out and illuminate the dust and gas in which they were born. 

The chords intensify a third time at a slightly higher pitch corresponding to the red-orange colors in the image, as the sound draws over the densest star-forming region of the frame. This stellar nursery is hidden by a layer of dust and gas that is so thick that it obscures almost all the light of the young stars within it.  

As the sound traces over the entire Euclid image, these different tones together form a cosmic symphony that represents the image of Messier 78, and the stars and galaxies that lie behind and within it.

Image Description: A filamentary orange veil covers a bright region of star formation. The background is dark, stippled with stars and galaxies ranging from small bright dots to starry shapes. The foreground veil spans from upper left to the bottom right and resembles a seahorse. Bright stars light up the ‘eye’ and ‘chest’ regions of the seahorse with purple light. Within the tail, three bright spots sit in a traffic-light like formation.

Aurora Australis in Antarctica | European Space Agency

Aurora Australis in Antarctica | European Space Agency

A mesmerizing display of Aurora Australis (southern lights) glows over the Concordia research station in Antarctica with yellow hues shimmering near the horizon and red lights stretching upwards into the vast polar sky.

These beautiful colors result from the interaction of charged particles from the Sun with gases in our atmosphere, guided by Earth's magnetic field to the polar regions. Green aurorae, the most common display, form at altitudes between 100 and 200 km, where oxygen atoms are highly concentrated and require less energy to emit light. During periods of high solar activity, charged particles become more energetic and can interact with oxygen at higher altitudes above 200 km, where oxygen atoms are less concentrated and need more energy to emit light. This higher energy corresponds to light with a longer wavelength, producing the stunning red aurorae. The beautiful yellow hues seen on the horizon occur when green and red aurorae mix in areas of overlap.

Standing beneath this incredible natural phenomenon is Jessica Studer, the European Space Agency-sponsored medical doctor for Concordia's 2024 winter-over. Jessica lived with a small team in complete isolation during the harsh Antarctic winter where the Sun does not rise for four months and temperatures plunge as low as –85°C. Concordia is one of the most remote places on Earth; the closest humans are at Russia's Vostok research station 600 km away, making it more isolated than the International Space Station. The station is an unique platform for research in fields like astronomy, glaciology, and human physiology, offering insights into how humans adapt to extreme isolation, cold, and darkness—conditions that mirror those faced by astronauts in space.

The aurorae visible here were captured in May 2024, during a period of heightened solar activity associated with the ongoing solar activity maximum, a phase in the Sun’s 11-year cycle that increases the intensity and frequency of auroral displays. These vibrant skies are just one of the benefits of living and working in Concordia, alongside the opportunity to contribute to groundbreaking science in a challenging environment.

Would you like to experience these breathtaking sights yourself? The European Space Agency (ESA) is currently accepting applications for a medical doctor to spend the winter of 2026 at Concordia station—apply here: https://bit.ly/3P4WXWc

Shenzhou-19 crew members aboard China's orbiting Tiangong Space Station successfully completed a marathon nine-hour spacewalk at 21:57 Beijing Time on Tuesday, December 17, 2024, setting a new long duration record for Chinese astronauts' extravehicular activities (EVAs). 

The previous record for the longest spacewalk in Earth orbit was set by the Russian space agency Roscosmos after its cosmonauts completed a spacewalk lasting 8 hours and 13 minutes in 2018. It was set by Expedition 54 Commander Alexander Misurkin and Flight Engineer Anton Shkaplerov of the International Space Station.

Astronauts Cai Xuzhe, Song Lingdong were assigned the EVA duty, while Wang Haoze assisted the pair throughout the mission from inside the space station. It was the 17th spacewalk carried out by Chinese astronauts.

At the end of the mission, before closing the hatch, the Shenzhou-19 crew expressed their joy at completing the mission and their gratitude to the ground team.

"Congratulations to 02 for completing your first spacewalk and moreover, for becoming the first Chinese astronaut born after 1990 to carry out EVAs. My appreciation also goes to the full collaboration of 03 inside the module, and to the extensive support of Shuguang and the entire technical team. From the assigned tasks to the more flexible assignments, we feel greater and greater confidence in conducting extravehicular activities. China's space station will always remain something to look forward to," said Cai, commander of Shenzhou-19 spaceflight mission crew.

"I express my gratitude to 01, Shuguang, and all the ground staff. Today, our crew and the ground team worked together to make the extravehicular activities a success. As I admired the spectacular view in space, I felt deep in my heart how important and great a cause the manned spaceflight is. I want to take this opportunity to thank all those who dedicate themselves to this cause—those who were here before us and who are with us along the way. Thank you all for your hard work, so that we were given the chance to conduct a spacewalk. The cause of the manned spaceflight is a relay race, and we are in it every step of the way. Let us keep striving and head for the future together," said Song.

"Congratulations to 01 and 02 for successfully completing your talks. Both of you made breakthroughs and I'm proud of your excellent performance. Meanwhile, my thanks also go to Shuguang and all the staff who worked day and night on this mission. Everybody up in space and on Earth work as one in our exploration and joint efforts for a promising tomorrow. I wish everyone sweet dreams tonight," Wang said.

China launched the Shenzhou-19 crewed spaceship on Oct. 30, 2024, sending three astronauts—including the country's first female space engineer—to its orbiting space station for a six-month mission.
