The Webb Space Telescope has captured a pair of intertwined galaxies glowing in the infrared. In this photo provided by NASA and the Space Telescope Science Institute, two interacting galaxies are captured by the Webb Space Telescope in the infrared. Scientists say the neighboring galaxies, nicknamed Penguin, right, and the Egg, left, have been tangled up for tens of millions of years. (NASA and Space Telescope Science Institute via AP) The observatory operated by NASA and the European Space Agency photographed the two galaxies 326 million light-years away, surrounded by a blue haze of stars and gas. A light-year is 5.8 trillion miles. The pictures, released Friday, marks the second anniversary of Webb’s science operations. The neighboring galaxies, nicknamed Penguin and the E...

NASA’s Webb Telescope depicts a new treasure trove of images with clearly defined arms It’s oh-so-easy to be absolutely mesmerized by these spiral galaxies. Follow their clearly defined arms, which are brimming with stars, to their centers, where there may be old star clusters and – sometimes – active supermassive black holes. Only NASA’s James Webb Space Telescope can deliver highly detailed scenes of nearby galaxies in a combination of near- and mid-infrared light – and a set of these images was publicly released today. These Webb images are part of a large, long-standing project, the Physics at High Angular resolution in Nearby GalaxieS (PHANGS) program, which is supported by more than 150 astronomers worldwide. Before Webb took these images, PHANGS was already brimming with data...

NASA on Monday named the first woman and the first African American ever assigned as astronauts to a lunar mission, introducing them as part of the four-member team chosen to fly on what would be the first crewed voyage around the moon in more than 50 years. Christina Koch, an engineer who already holds the record for the longest continuous spaceflight by a woman and was part of NASA's first three all-female spacewalks, was named as a mission specialist for the Artemis II lunar flyby expected as early as next year. People gather ahead of an event of NASA to announce the crew of the Artemis II space mission to the moon and back in Houston, Texas, U.S., April 3, 2023.

What happened when NASA’s DART collided with asteroid Dimorphos

First results are out from ESO telescopes on the aftermath of asteroid impact Using ESO’s Very Large Telescope (VLT), two teams of astronomers have observed the aftermath of the collision between NASA’s Double Asteroid Redirection Test (DART) spacecraft and the asteroid Dimorphos. The controlled impact was a test of planetary defence, but also gave astronomers a unique opportunity to learn more about the asteroid’s composition from the expelled material. This series of images, taken with the MUSE instrument on ESO’s Very Large Telescope, shows the evolution of the cloud of debris that was ejected when NASA’s DART spacecraft collided with the asteroid Dimorphos. The first image was taken on 26 September 2022, just before the impact, and the last one was taken almost one month later o...

Volcanoes on Venus? ‘Striking’ finding hints at modern-day activity

Discovery highlights need for future missions after NASA puts one on hold Scientists have found some of the strongest evidence yet that there is volcanic activity on Venus. Because the planet is a close neighbour to Earth and originally had water on its surface, one big question has been why its landscape is hellish while Earth’s is habitable. Learning more about its volcanic activity could help explain its evolution — and Earth’s. Scientists have known that Venus is covered in volcanoes, but whether or not any of them is still active has been long debated. Now, researchers have discovered that at least one of them probably is, by examining radar images of the planet’s surface collected by NASA’s Magellan spacecraft between 1990 and 1992. They determined that a volcanic vent located...

Hubble finds hungry black hole twisting captured star into donut shape

Black holes are gatherers, not hunters. They lie in wait until a hapless star wanders by. When the star gets close enough, the black hole's gravitational grasp violently rips it apart and sloppily devours its gasses while belching out intense radiation. Astronomers using NASA's Hubble Space Telescope have recorded a star's final moments in detail as it gets gobbled up by a black hole. These are termed "tidal disruption events." But the wording belies the complex, raw violence of a black hole encounter. There is a balance between the black hole's gravity pulling in star stuff, and radiation blowing material out. In other words, black holes are messy eaters. Astronomers are using Hubble to find out the details of what happens when a wayward star plunges into the gravitational abyss. ...

NASA’s Orion capsule returns to Earth, capping Artemis I flight around moon

NASA's Orion capsule barreled through Earth's atmosphere and splashed down in the Pacific ocean on Sunday after making an uncrewed voyage around the moon, winding up the inaugural mission of the U.S. agency's new Artemis lunar program 50 years to the day after Apollo's final moon landing. The gumdrop-shaped Orion capsule, carrying a simulated crew of three mannequins wired with sensors, plunked down in the ocean at 9:40 a.m. PST (1740 GMT) off Mexico's Baja California peninsula, demonstrating a high-stakes homecoming before NASA flies its first crew of Artemis astronauts around the moon in the next few years. U.S. Navy divers attach winch cables to NASA's Orion capsule after being successfully secured by a NASA and U.S. Navy team, off the coast of Baja California, Mexico, 11 Decembe...

NASA’s next-generation Artemis rocket lifts off on test flight to moon

NASA's towering next-generation moon rocket blasted off from Florida early on Wednesday on its debut flight, a crewless voyage inaugurating the U.S. space agency's Artemis exploration program 50 years after the final Apollo moon mission. The 32-story Space Launch System (SLS) rocket surged off the launch pad from the Kennedy Space Center in Cape Canaveral at 1:47 a.m. EST (0647 GMT), to send its Orion capsule on a three-week test journey around the moon and back without astronauts aboard. About 90 minutes after launch, the rocket's upper stage fired thrusters for a "trans-lunar injection" burn propelling Orion out of Earth orbit on course for the moon. That put the capsule on track for a 25-day flight that will bring it to within 60 miles (97 km) of the lunar surface before sailing ...

NASA’s Webb takes star-filled portrait of Pillars of Creation

October 25, 2022764 Views

Near-infrared light uncovers vast populations of forming stars, many still encased in dust NASA’s James Webb Space Telescope has captured a lush, highly detailed landscape – the iconic Pillars of Creation – where new stars are forming within dense clouds of gas and dust. The three-dimensional pillars look like majestic rock formations, but are far more permeable. These columns are made up of cool interstellar gas and dust that appear – at times – semi-transparent in near-infrared light. This image of the Pillars of Creation, captured by Webb’s Near-Infrared Camera (NIRCam), shows compass arrows, scale bar, and color key for reference. It lies within the Eagle Nebula, which is also known as Messier 16 (M16). The north and east compass arrows show the orientation of the image on the s...

NASA calls off retry of Artemis moon rocket launch, citing fuel leak

For the second time in five days, NASA on Saturday halted a countdown in progress and postponed a planned attempt to launch the debut test flight of its giant, next-generation rocket, the first mission of the agency's moon-to-Mars Artemis program. The latest attempt to launch the 32-story-tall Space Launch System (SLS) rocket and its Orion capsule was scrubbed after repeated failed attempts by technicians to fix a leak of super-cooled liquid hydrogen propellant being pumped into the vehicle's core-stage fuel tanks. Pre-flight operations were officially called off for the day by Artemis I launch director Charlie Blackwell-Thompson about three hours before the targeted two-hour launch window was due to open at 2:17 p.m. EDT (1817 GMT). NASA's next-generation moon rocket, the Space ...
