Nebula NGC 6153 is 4,000 lightyears away, located in the constellation of Scorpius. The elliptical cloud is the remains of the star that was once there, all its remains ejected once it ran out of fuel. »
Earlier this year, NASA’s MESSENGER mission continued to take photos of Mercury right up until it crashed into the planet. This enhanced image of the usually grey-looking planet shows how color doesn’t quite capture the diversity of the planet’s make up. »
It’s full of galaxies! This new image from the Hubble Space Telescope and the ESO’s New Technology Telescope shows four of the seven galaxies in the galaxy group HCG 16: NGC 839, NGC 838, NGC 835, and NGC 833. Check out those glowing centers and wispy tails of gas! »
This past weekend, the Philae Lander awoke from its 211-day hibernation on Comet 67P/Churyumov–Gerasimenko. The dramatic receipt of signals from the probe triggered renewed activity among mission planners who are now trying to figure out what to do next. Here’s how things could unfold.
The sphere surrounding the Milky Way is called the Local Volume, and it is 35 million lightyears in diameter. In the Local Volume is PGC 18431, a galaxy the Hubble caught as part of a mission to figure out how galaxies cluster and move. »
After months of searching, the European Space Agency says it may have finally caught a glimpse of the missing Philae Lander on the surface of Comet 67P/Churyumov-Gerasimenko. »
On June 11, Samantha Cristoforetti will return to Earth after two hundred days on the International Space Station. She’ll be setting a record for length of a single mission for ESA astronauts, Italian astronauts and all female astronauts. »
Five light years wide, but over 280 lightyears in length, the G49 filament winds through space. Where it is brightest, it is also coolest, and that’s where stars are being created. »
Near the middle of this photo from the High Resolution Stereo Camera on the European Space Agency’s Mars Express is the Siloe Patera. Siloe Patera lies in the Arabia Terra region of Mars, and measures 20 km by 40 km. Recent research suggests it could be the remains of a supervolcano. »
Using the OSIRIS camera aboard the Rosetta spacecraft, ESA scientists have discovered a strange formation of what appears to be balancing boulders on comet 67P/Churyumov-Gerasimenko.
Nearly half of Italy’s population lives in the Po Vally, captured here on a Sentinel-1A image. The brightest spot, on the far left, is Milan. Along the bottom of the image, cities cluster along a highway. »
Last week, NASA’s Messenger spacecraft ended its 11-year mission by crashing into Mercury. Of course, Messenger was doomed anyway, but sometimes a mission’s entire point is to smash one thing into a bigger thing and watch the explosion. »
This Hubble Telescope image has several galaxies floating through it, but at the center is UGC 5797, which is currently making stars to populate itself. The blue glow indicates prolific star formation, and, in this image, you can even pick out large blue stars that result. »
Over the course of April 28–29, a gigantic filament, briefly suspended above the surface* of the sun, broke off and created an enormous snakelike eruption of plasma that extended millions of miles out into space. The event was both powerful and beautiful, another demonstration of the incredible energy and activity of… »
Why does space have structure? Why does our universe have not only stars, but galaxies and galactic clusters? Researchers recently identified 234 potential proto-clusters: candidates for early galactic clusters from when the universe was just 3 billion years old that may help solve this astrophysical mystery. »
The Hubble Space Telescope shows us the edge-view of galaxy NGC 5023. Even though NGC 5023 is a spiral galaxy, its orientation to the Hubble means that we can't see its arms, only a side view which shows us a disk. »
