Sun Releases Strong X3.3 Solar Flare | NASA’s Solar Dynamics Observatory

Sun Releases Strong X3.3 Solar Flare | NASA’s Solar Dynamics Observatory

The Sun emitted a strong solar flare, peaking at 11:57 p.m. ET on Oct. 23, 2024. NASA’s Solar Dynamics Observatory (SDO) watches the Sun constantly and captured images of the event.

A portion of the Sun fills the center, most of the top, and right side of the image. The left of the image is black. The Sun is dark orange with bright yellow areas. From a very bright yellow area, solar material bursts off the Sun, into the area of black space.

NASA’s Solar Dynamics Observatory captured these images of a solar flare—seen as the bright flash on the left—on Oct. 23, 2024. The image shows a subset of extreme ultraviolet light that highlights the extremely hot material in flares that is colorized in orange.

Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts.

This flare is classified as an X3.3 class flare. X-class denotes the most intense flares, while the number provides more information about its strength.

Pan of Spiral Galaxy Messier 90: Best View Yet | Hubble Space Telescope

Pan of Spiral Galaxy Messier 90: Best View Yet | Hubble Space Telescope

This striking spiral galaxy is Messier 90 (M90, also NGC 4569), located in the constellation Virgo. In 2019, an image of M90 was released using data from the older Wide Field and Planetary Camera 2—data taken in 1994 soon after the camera’s installation. That image has a distinctive stair-step pattern due to the layout of WFPC2’s sensors. WFPC2 was replaced in 2010 by the Wide Field Camera 3, and Hubble used WFC3 when it turned its aperture to Messier 90 again in 2019 and 2023. The resulting data was processed to create this stunning new image, providing a much fuller view of the galaxy’s dusty disc, its gaseous halo and its bright core.

The inner regions of M90’s disc are sites of star formation. This is highlighted here by red H-alpha light from nebulae, but this is absent in the rest of the galaxy. M90 sits among the galaxies of the relatively nearby Virgo Cluster, and the course of its orbit took it on a path near the cluster’s centre about three hundred million years ago. The density of gas in the inner cluster weighed on M90 like a strong headwind, stripping enormous quantities of gas from the galaxy and creating the diffuse halo that can be seen around it here. This gas is no longer available for M90 to form new stars with, and it will eventually fade as a spiral galaxy as a result.

M90 is located 55 million light-years from Earth, but it is one of the very few galaxies getting closer to us. Its orbit through the Virgo cluster has accelerated it so much that it is in the process of escaping the cluster entirely, and by happenstance it is moving in our direction—other galaxies in the Virgo cluster have been measured at similar speeds, but in the opposite direction. Over the coming billions of years, we will be treated to a yet better view of M90 while it evolves into a lenticular galaxy.

Image Description: A spiral galaxy. It has a bright core with light spilling out, and its disc is filled with thick clumps of dark reddish dust that swirls around the galaxy following its rotation. Parts of the disc are speckled with blue, showing brighter and hotter stars. A halo of faintly-lit gas wraps around the galaxy, extending beyond the edges of the image.

Journey to Young Star Cluster NGC 602 in Hydrus | James Webb Space Telescope

Journey to Young Star Cluster NGC 602 in Hydrus | James Webb Space Telescope

This video takes the viewer to the Small Magellanic Cloud galaxy roughly 200,000 light-years from Earth, featuring the young star cluster NGC 602. This new image is from the NASA/European Space Agency/Canadian Space Agency James Webb Space Telescope. The image includes data from Webb’s Near-InfraRed Camera (NIRCam) and  Mid-InfraRed Instrument (MIRI).

The local environment of this cluster is a close analog of what existed in the early Universe with very low abundances of elements heavier than hydrogen and helium. The existence of dark clouds of dense dust and the fact that the cluster is rich in ionized gas also suggest the presence of ongoing star formation processes. This cluster provides a valuable opportunity to examine star formation scenarios under dramatically different conditions from those in our solar neighborhood.

An international team of astronomers, including Peter Zeidler, Elena Sabbi, and Antonella Nota, used Webb to observe NGC 602 and detected candidates for the first young brown dwarfs outside our Milky Way.

The Bright Blue Star Spica in Virgo | New Forest Observatory

The Bright Blue Star Spica in Virgo | New Forest Observatory

Shown here is spectacular Spica, the lead star in the constellation Virgo and the brightest blue star in the entire night sky. This photo was taken from the New Forest Observatory, U.K., on May 5, 2024. Viewed through a pair of decent binoculars, Spica's intense blue color, when its high in the sky, becomes quite obvious. Its B-V index (an indication of the redness or blueness of a star) is -0.23. Only 3 stars in the sky are bluer, but none are as bright.

Spica has a magnitude of 0.98.

Distance: 250 light years

It is a spectroscopic binary star and rotating ellipsoidal variable—a system whose two stars are so close together they are egg-shaped rather than spherical, and can only be separated by their spectra. The primary is a blue giant and a variable star of the Beta Cephei type.

Supermoon over Ohio

Supermoon over Ohio

This Supermoon was visible on September 17th, 2024, in Cleveland, Ohio, USA. On this day, the full moon was a partial lunar eclipse; a supermoon; and a harvest moon. A “supermoon” occurs when a full Moon coincides with the Moon’s closest approach to Earth in its elliptical orbit, a point known as perigee. During every 27-day orbit around Earth, the Moon reaches both its perigee, about 226,000 miles (363,300 km) from Earth, and its farthest point, or apogee, about 251,000 miles (405,500 km) from Earth. Because the Moon’s orbit wobbles and differs depending on where the Sun and Earth are in their orbits, the exact distance of these closest and furthest points varies, with supermoons occurring closer or farther than others. 

“Supermoon" is not an official astronomical term, but typically it is used to describe a full Moon that comes within at least 90 percent of perigee. Supermoons only happen three to four times a year, and always appear consecutively. Throughout most of Earth's orbit around the sun, perigee and the full Moon do not overlap.

Shenzhou-19 Spacecraft & Rocket Rollout to Launchpad | China Space Station

Shenzhou-19 Spacecraft & Rocket Rollout to Launchpad | China Space Station

 

The combination of the Shenzhou-19 crewed spaceship and a Long March-2F Y19 carrier rocket has been successfully transferred to the launching area at the Jiuquan Satellite Launch Center in northwest China on Tuesday afternoon, Oct. 22, 2024.

At 16:00, the combination was lifted from the assembly and test facility and smoothly transported via a vertical transfer method to the launch site. The entire transfer process covered a distance of 1.5 kilometers and took approximately two hours.

The spacecraft and rocket combination weighs over 40 tons and stands nearly 60 meters tall.

The completion of this vertical transport signifies that the rocket has officially entered the final phase of launch preparations.

Subsequent activities will include a series of function checks and joint tests, with a launch expected to take place later this month.

Gao Minzhong, a senior engineer with the Jiuquan Satellite Launch Center, highlighted the emphasis on safety and precision during the transport.

"We have optimized the control of positioning accuracy upon the combination's arrival at the destination and prepared multiple backup plans to guarantee a reliable and foolproof transfer," Gao said.

China is scheduled to launch the Shenzhou-19 crewed spaceship and welcome the Shenzhou-18 crew back to the Earth in late October, according to the China Manned Space Agency (CMSA).

The three-member Shenzhou-18 crew was sent into space on April 25.

Shenzhou-19 Crewed Spacecraft Prepared for Launch | China Space Station

Shenzhou-19 Crewed Spacecraft Prepared for Launch | China Space Station

The combination of the Shenzhou-19 crewed spacecraft atop its Long March-2F Y18 carrier rocket was made ready for the imminent vertical transfer to the launching area at the Jiuquan Satellite Launch Center in northwest China on Tuesday, October 21, 2024.

At around 15:00 on Tuesday, the technical staff at the assembly test building were making final checks before transferring the combination to the launching pad 1.5 kilometers away.

The engineers had completed the removal of the air supply hose from the rocket fairing, and cleaned, closed and inspected all the connections between the fairing and the outside to ensure that the inside of the fairing is safely isolated from the outside environment during the transfer.

In an interview with CCTV, Gao Minzhong, senior engineer with the Jiuquan Satellite Launch Center, detailed more preparatory work at the final assembly test building ahead of the transfer.

"The pre-transfer work can be summarized into four major aspects. The first is the check and test of the rocket and escape tower in the technical area. The second is the propellant filling and cylinders filling of the spacecraft. The third is to dock the spacecraft escape tower and the assembled rocket assembly to form a spacecraft-rocket-escape tower combination. And the fourth is to complete all the preparatory work before the transfer today. Now, each system is working smoothly, and the preparatory work has been completed. The conditions for vertical transfer are in place," Gao said.

The combination is set to move towards the launching pad at around 16:00 on a mobile launch platform along a seamless rail. The engineer noted that the timing of the transfer depends mainly on the temperature, wind speed and track conditions.

The ideal temperature is 0 to 30 degrees Celsius, and the conditions at the Jiuquan Satellite Launch Center are just right, according to Gao.

"The total height of the spaceship-rocket-escape tower combination on the mobile launch platform is nearly 70 meters, so there are relatively strict requirements for the wind speed, which should be controlled to below 10 meters per second. There is a 1.5-kilometer specially-built track for vertical transfer from the assembling building to the launch pad. The transfer has high requirements for the track gauge, flatness and straightness, with millimeter-level accuracy," Gao explained.

China is scheduled to launch the Shenzhou-19 crewed spaceship and welcome the Shenzhou-18 crew back to the Earth in late October, according to the China Manned Space Agency earlier this month.

The three-member Shenzhou-18 crew was sent into space on April 25.

Globular Star Cluster Messier 5 in Serpens Caput: Surprising 'Vitality' | Hubble

Globular Star Cluster Messier 5 in Serpens Caput: Surprising 'Vitality' | Hubble

The globular cluster Messier 5, shown here in this NASA/European Space Agency Hubble Space Telescope image, is one of the oldest belonging to the Milky Way galaxy. The majority of its stars formed more than 12 billion years ago, but there are unexpected newcomers on the scene, adding vitality to this aging population.

Stars in globular clusters form in the same stellar nursery and grow old together. The most massive stars age quickly, exhausting their fuel supply in less than a million years, and end their lives in spectacular supernovae explosions. This process should have left the ancient cluster Messier 5 with only old, low-mass stars. These stars have aged and cooled and have become red giants, while the oldest stars have evolved even further into blue horizontal branch stars.

Yet astronomers have spotted many young, blue stars in this cluster, hiding amongst the much more luminous ancient ones. Astronomers think that these laggard youngsters, called blue stragglers, were created either by stellar collisions or by the transfer of mass between binary stars. Such events are easy to imagine in densely populated globular clusters where a few million stars are tightly packed together.

Messier 5 lies at a distance of about 25,000 light-years in the constellation of Serpens (The Snake). This image was taken with the Wide Field Channel of Hubble’s Advanced Camera for Surveys. The picture was created from images taken through a blue filter (F435W, colored blue), a red filter (F625W, colored green) and a near-infrared filter (F814W, colored red). The total exposure times per filter were 750 s, 400 s and 567 s, respectively. The field of view is about 2.6 arcminutes across.

Comet C/2023 A3 over California's Sierra Mountains with M5 Star Cluster

Comet C/2023 A3 over California's Sierra Mountains with M5 Star Cluster

The tails of Comet Tsuchinshan-ATLAS were a sight to behold. Pictured, C/2023 A3 (Tsuchinshan–ATLAS) was captured near peak impressiveness last week over the Eastern Sierra Mountains in California, USA. The comet had a bright tail, along with a distinct anti-tail pointing in nearly the opposite direction. The globular star cluster M5 can be seen on the right, far in the distance. As it approached the sun, it was unclear if this comet, a crumbling iceberg, would disintegrate completely as it warmed in the bright sunlight. In reality, the comet survived to become brighter than any star in the night (magnitude -4.9), but unfortunately was then so nearly in front of the Sun that it was hard for many casual observers to locate. Whether Comet Tsuchinshan-Atlas becomes known as the Great Comet of 2024 now depends, in part, on how impressive incoming comet C/2024 S1 (ATLAS) becomes over the next two weeks.

C/2023 A3 (Tsuchinshan–ATLAS) is a comet from the solar system's Oort cloud discovered by the Purple Mountain Observatory east of Nanjing, China, on January 9, 2023, and independently found by the automated Asteroid Terrestrial-impact Last Alert System (ATLAS) in South Africa on February 22, 2023. ATLAS is funded by NASA's planetary defense office, and developed and operated by the University of Hawaii's Institute for Astronomy. C/2023 A3 passed perihelion (closest approach to the Sun) at a distance of 0.39 AU (58 million km; 36 million miles) on September 27, 2024.

The Oort cloud is theorized to be a vast cloud of icy planetesimals surrounding the Sun at distances ranging from 2,000 to 200,000 AU (0.03 to 3.2 light-years). The concept of such a cloud was proposed in 1950 by the Dutch astronomer Jan Oort, in whose honor the idea was named. Oort proposed that the bodies in this cloud replenish and keep constant the number of long-period comets entering the inner Solar System—where they are eventually consumed and destroyed during close approaches to the Sun.
