Marking the 100th anniversary of the Rocky Mountain National Park on Jan. 26, 2015, Expedition 42 Flight Engineer Terry Virts posted this photograph, taken from the International Space Station, to Twitter. Virts wrote, “Majestic peaks and trails! Happy 100th anniversary @RockyNPS So much beauty to behold in our @NatlParkService.”
In this image, an expanding shell of debris called SNR 0519-69.0 is left behind after a massive star exploded in the Large Magellanic Cloud, a satellite galaxy to the Milky Way. Multimillion degree gas is seen in X-rays from Chandra, in blue. The outer edge of the explosion (red) and stars in the field of view are seen in visible light from the Hubble Space Telescope.
This July 20, 1969 photograph of the interior view of the Apollo 11 Lunar Module shows astronaut Edwin E. “Buzz” Aldrin, Jr. during the lunar landing mission. The picture was taken by astronaut Neil A. Armstrong, commander, prior to the landing.
If you visit HH 24, don’t go near the particle beam jet. This potential future travel advisory might be issued because the powerful jet likely contains electrons and protons moving hundreds of kilometers per second. The above image was taken by the Hubble Space Telescope in infrared light in order to better understand turbulent star forming regions known as Young Stellar Objects (YSOs).
Discovered in August of 2014, Comet Lovejoy is currently sweeping north through the constellation Taurus, bright enough to offer good binocular views. Glowing softly with a greenish hue, Comet Lovejoy passed closest to planet Earth on January 7, while its perihelion (closest point to the Sun) will be on January 30. Classed as a long period comet, it should return again … in about 8,000 years.
SpaceX’s Falcon 9 rocket lifts off from Space Launch Complex 40 at Cape Canaveral Air Force Station carrying the Dragon resupply spacecraft to the International Space Station. Liftoff was at 4:47 a.m. EST on Saturday, Jan. 10, 2015.
Coronal holes are regions of the corona where the magnetic field reaches out into space rather than looping back down onto the surface. Particles moving along those magnetic fields can leave the sun rather than being trapped near the surface. Those trapped particles can heat up and glow, giving us the lovely AIA images. In the parts of the corona where the particles leave the sun, the glow is much dimmer and the coronal hole looks dark.
Globular clusters are tightly bound groups of stars which orbit galaxies. The large mass in the rich stellar center of the globular cluster pulls the stars inward to form a ball of stars. The word globulus, from which these clusters take their name, is Latin for small sphere.
Expedition 42 Flight Engineer Samantha Cristoforetti of the European Space Agency (ESA) took this photograph of the Alps from the International Space Station, and posted it to social media on Tuesday, Dec. 23, 2014. She wrote, “I’m biased, but aren’t the Alps from space spectacular? What a foggy day on the Po plane, though! #Italy”. Image Credit: NASA/ESA/Samantha Cristoforetti
This new NASA/ESA Hubble Space Telescope image shows the galaxy IC 335 in front of a backdrop of distant galaxies. IC 335 is part of a galaxy group containing three other galaxies, and located in the Fornax Galaxy Cluster 60 million light-years away.
The sun emitted a significant solar flare, peaking at 7:28 p.m. EST on Dec. 19, 2014. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event. Solar flares are powerful bursts of radiation.
