The California Nebula in Perseus

The California Nebula in Perseus

This is the California Nebula (NGC 1499) in the constellation of Perseus. The image was reprocessed to reduce the impact of the stars in the original image. Doing so really makes this nebula "pop."

The California Nebula somewhat resembles the shape of the state of California—evidently enough to give it its name. It is an emission nebula, lying approximately 1,000 to 1,500 light years from Earth. Xi Persei, the bright star just below NGC 1499 at right center, is sufficiently close to ionize the nebula's hydrogen atoms, giving it a noticeably reddened glow.

Image Details: Photo taken on Sky90 MiniWASP array at New Forest Observatory in Fall 2022. Image consists of 16-hours' worth of 15-minute subs.

Northern Lights, The Moon, Venus & Possible STEVE Event | Earth Science

Northern Lights, The Moon, Venus & Possible STEVE Event | Earth Science

Lucy Spring: "Earlier this spring, we had quite a spectacular show of Northern Lights here in the northwestern portion of lower Michigan. I was with fellow photographer friends in the Sleeping Bear Dunes National Lakeshore Area, at Sleeping Bear Point, and captured the above photo of the purplish streak at right center, which appears to be a phenomenon known as STEVE, short for Strong Thermal Emission Velocity Enhancement. Unlike other auroras, the STEVE seems to form from a ribbon of hot gases. From our vantage point, it was separate from the end of the green auroral arc in the southwestern sky, at lower right. Whether or not this was in fact a STEVE event, it was an amazing night of observing the northern lights! Note that the Moon and Venus are at the lower left center of the frame. Photo taken on March 23, 2023."

Planet Mars: Flight over Korolev Crater | European Space Agency's Mars Express

Planet Mars: Flight over Korolev Crater | European Space Agency's Mars Express

This video, based on images taken by the European Space Agency’s Mars Express, showcases the 82 km wide Korolev crater on Mars. Located in the northern lowlands of the Red Planet, south of the large Olympia Undae dune field that partly surrounds Mars’ north polar cap, this well-preserved impact crater is filled with water ice all year round. The crater’s floor lies two kilometers below its rim, enclosing a 1.8 km thick domed deposit that represents a large reservoir of non-polar ice on Mars. 

Water ice is permanently stable within Korolev crater because the deepest part of this depression acts as a natural cold trap. The air above the ice cools and is thus heavier compared to the surrounding air. Since air is a poor conductor of heat, the water ice mound is effectively shielded from heating and sublimation.

This video was created using an image mosaic made from single orbit observations from the High Resolution Stereo Camera (HRSC) on Mars Express. The mosaic combines data from the HRSC nadir and color channels; the nadir channel is aligned perpendicular to the surface of Mars, as if looking straight down at the surface. The mosaic image was then combined with topography information from the stereo channels of HRSC to generate a three-dimensional landscape, which was then recorded from different perspectives, as with a movie camera, to render the flight shown in the video.

Planet Mars: Korolev Crater | European Space Agency's Mars Express

Planet Mars: Korolev Crater | European Space Agency's Mars Express

This image from the European Space Agency’s Mars Express shows Korolev crater, an 82-kilometer-across feature found in the northern lowlands of Mars.

This plan mosaic comprises five different observational strips that have been combined to form a single image, gathered over orbits 18042 (captured on 4 April 2018), 5726, 5692, 5654, and 1412. It covers a region centred at 165° E, 73° N, and has aresolution of approximately 21 metres per pixel. 

This image was created using data from the nadir and color channels of the High Resolution Stereo Camera (HRSC). The nadir channel is aligned perpendicular to the surface of Mars, as if looking straight down at the surface.

Mars Express has now been in space for two decades, despite a planned initial lifetime of just 687 Earth days. It has achieved its aforementioned aims and revealed a wealth of knowledge about Mars in that time, making it undeniably one of the most successful missions ever sent to the Red Planet.

The orbiter will continue its study of Mars until at least the end of 2026, with an indicative extension from January 1, 2027 to December 31, 2028 to support the JAXA-led Mars Moons eXploration (MMX) mission (Japan), followed by two years of post-operations.

The Busy Center of The Lagoon Nebula | Hubble

The Busy Center of The Lagoon Nebula | Hubble

The center of the Lagoon Nebula is a whirlwind of spectacular star formation. Visible near the image center, at least two long funnel-shaped clouds, each roughly half a light-year long, have been formed by extreme stellar winds and intense energetic starlight. A tremendously bright nearby star, Herschel 36, lights the area. Vast walls of dust hide and redden other hot young stars. As energy from these stars pours into the cool dust and gas, large temperature differences in adjoining regions can be created generating shearing winds which may cause the funnels. 

This picture, spanning about 15 light years, combines images taken in four colors by the orbiting Hubble Space Telescope. The Lagoon Nebula, also known as M8, lies about 5000 light years distant toward the constellation of the Archer (Sagittarius).

Euclid: The European Space Agency’s Mission into the Unknown

Euclid: The European Space Agency’s Mission into the Unknown

 

The European Space Agency’s Euclid mission is designed to bring the dark side of the Universe to light. Based on the way galaxies rotate and orbit one another, and the way in which the Universe is expanding, astronomers believe that two unseen entities dominate the composition of our cosmos. They call these mysterious components dark matter and dark energy, yet to date we have not been able to detect either of them directly, only inferring their presence from the effects they have on the Universe at large.

To better understand what dark matter and dark energy may be, we need a mission that can more closely reveal what effects they have had on galaxies, galaxy clusters and the expansion of the Universe itself. Euclid is that mission.

The European Space Agency’s Euclid mission will create a 3D-map of the Universe, with the third dimension representing time itself. The further away a galaxy is located, the longer its light has taken to reach us and so the earlier in cosmic history we will see it. By observing billions of galaxies out to a distance of 10 billion light-years, scientists will be able to chart the position and velocity of galaxies over immense distances and through most of cosmic history, and trace the way the Universe has expanded during that time. Euclid’s extraordinary optics will also reveal subtle distortions in the appearance of galaxies.

From this wealth of new data, astronomers will be able to infer the properties of dark energy and dark matter more precisely than ever before. This will help theorists pin down the nature of these mysterious components and develop a refined understanding of how gravity behaves at the largest distances.

Globular Star Cluster NGC 6544 in Sagittarius | Hubble

Globular Star Cluster NGC 6544 in Sagittarius | Hubble

The teeming stars of the globular cluster NGC 6544 glisten in this image from the NASA/European Space Agency Hubble Space Telescope. This cluster of tightly bound stars lies more than 8,000 light-years away from Earth and is—like all globular clusters—a densely populated region of tens of thousands of stars.

Image Description: A cluster of stars in warm and cool colors. The whole view is filled with small stars, which become much denser and brighter around a core just right of center. Most of the stars are small, but some are larger with a round, brightly-colored glow and four sharp diffraction spikes. Behind the stars, a dark background can be seen.

This image of NGC 6544 combines data from two of Hubble’s instruments—the Advanced Camera for Surveys and Wide Field Camera 3—as well as two separate astronomical observations. The first observation was designed to find a visible counterpart to the radio pulsar discovered in NGC 6544. A pulsar is the rapidly spinning remnant of a dead star, emitting twin beams of electromagnetic radiation like a vast astronomical lighthouse. This pulsar rotates particularly quickly, and astronomers turned to Hubble to help determine how this object evolved in NGC 6544. 

The second observation which contributed data to this image was also designed to find the visible counterparts of objects detected at other electromagnetic wavelengths. Instead of matching up sources to a pulsar, however, astronomers used Hubble to search for the counterparts of faint X-ray sources. Their observations could help explain how clusters like NGC 6544 change over time.

NGC 6544 lies in the constellation Sagittarius, close to the vast Lagoon Nebula, a hazy labyrinth of gas and dust sculpted by the fierce winds of newly born stars.

NASA Astronaut Sally Ride: First American Woman in Space—40th Anniversary

On June 18, 1983, NASA Astronaut Sally K. Ride became the first American woman in space, when she launched with her four crewmates aboard the Space Shuttle Challenger on mission STS-7. Ride and five other women had been selected in 1978 for NASA Astronaut Group 8, the first American selection class to include women. With the advent of the space shuttle, NASA expanded astronaut selection from only pilots to scientists and engineers, and women became eligible for selection. NASA announced Ride and her classmates to the public on Jan. 16, 1978.

Ride served as Capsule Communicator (CAPCOM) for STS-2 and STS-3 in late 1981 and early 1982, and became an expert in the use of the shuttle’s robotic arm. On April 30, 1982, NASA announced that Ride would serve as a Mission Specialist on STS-7, a satellite deployment and retrieval mission on board the Space Shuttle Challenger. Her crewmates were Commander Robert L. Crippen, Pilot Frederick H. “Rick” Hauck, and Mission Specialist John M. Fabian. NASA added physician-astronaut Norman E. Thagard to the crew in January 1983. Thagard’s addition then marked the largest crew flown in a single spacecraft to date.

During the six-day mission, the most complex in the shuttle program at that time, the crew launched two commercial communications satellites, Anik C3 for Canada’s Telesat and Palapa B2 for Indonesia. Ride used the Shuttle’s robotic arm to deploy the first Shuttle Pallet Satellite (SPAS-01) and retrieve it two days later, the first time the Shuttle was used to return a spacecraft to Earth. 

Ride’s launch on STS-7 occurred almost to the day of the 20th anniversary of the launch of the first woman in space, Soviet cosmonaut Valentina V. Tereshkova. Tereshkova launched into space June 16, 1963, aboard Vostok-6 using the call sign Chaika (чайка), or Seagull. She circled the Earth 48 times over three days and made a successful parachute landing June 19, 1963.

Sally Ride and Valentina Tereshkova made their marks on history.  Despite the camaraderie between astronauts and cosmonauts even during the height of the Cold War and the thaw afterwards, there’s no indication that the two ever met.  In their own ways, the two were trailblazers for women who followed their footsteps.

A busy patch of The Great Attractor | Hubble

A busy patch of The Great Attractor | Hubble


A busy patch of space has been captured in this image from the NASA/European Space Agency Hubble Space Telescope. Scattered with many nearby stars, the field also has numerous galaxies in the background.

Located on the border of Triangulum Australe (The Southern Triangle) and Norma (The Carpenter’s Square), this field covers part of the Norma Cluster (Abell 3627) as well as a dense area of our own galaxy, The Milky Way.

The Norma Cluster is the closest massive galaxy cluster to the Milky Way, and lies about 220 million light-years away. The enormous mass concentrated here, and the consequent gravitational attraction, mean that this region of space is known to astronomers as The Great Attractor, and it dominates our region of the Universe.

The largest galaxy visible in this image is ESO 137-002, a spiral galaxy seen edge on. In this image from Hubble, we see large regions of dust across the galaxy’s bulge. What we do not see here is the tail of glowing X-rays that has been observed extending out of the galaxy—but which is invisible to an optical telescope like Hubble.

Observing The Great Attractor is difficult at optical wavelengths. The plane of The Milky Way—responsible for the numerous bright stars in this image—both outshines (with stars) and obscures (with dust) many of the objects behind it. There are some tricks for seeing through this—infrared or radio observations, for instance—but the region behind the center of the Milky Way, where the dust is thickest, remains an almost complete mystery to astronomers.

This image consists of exposures in blue and infrared light taken by Hubble’s Advanced Camera for Surveys.

Spiral Galaxy ESO 137-001 | Hubble Space Telescope

Spiral Galaxy ESO 137-001 | Hubble Space Telescope


This Hubble image shows spiral galaxy ESO 137-001, framed against a bright background as it moves through the heart of galaxy cluster Abell 3627. Distance: 220 million light years

This image not only captures the galaxy and its backdrop in stunning detail, but also something more dramatic—intense blue streaks streaming outwards from the galaxy, seen shining brightly in ultraviolet light.

These streaks are in fact hot, wispy streams of gas that are being torn away from the galaxy by its surroundings as it moves through space. This violent galactic disrobing is due to a process known as ram pressure stripping—a drag force felt by an object moving through a fluid. For this reason, ESO 137-001 is also described as a "jellyfish" galaxy.
