The bright streak of glowing gas and stars in this NASA/ESA Hubble Space Telescope image is known as PGC 51017, or SBSG 1415+437. It is a type of galaxy known as a blue compact dwarf.
This particular dwarf is well studied and has an interesting star formation history. Astronomers initially thought that SBS 1415+437 was a very young galaxy currently undergoing its very first burst of star formation, but more recent studies have suggested that the galaxy is in fact a little older, containing st [...]
Commander Terry Virts was the maintenance man Friday as he inspected windows and checked for dust buildup in vents inside the Destiny lab module. Virts also conducted more plumbing work, replacing a recycle tank in the Water Recovery System.
Italian astronaut Samantha Cristoforetti was in Europe’s Columbus lab module continuing her week-long science activities in the BioLab. She ran the TripleLux-B experiment using the BIoLab’s glovebox for the second time this week to study cellular mech [...]
Today's date marks an Equinox and a New Moon. Remarkably, while the exact timing of both geocentric events occur within a span of only 13 hours, the moon also reaches its new phase only 14 hours after perigee, the closest point in its orbit. That makes the Equinox New Moon the largest New Moon of 2015, though hard to see since that lunar phase presents the Moon's dark, night side to planet Earth.
Still, in this well composed image of a young lunar phase from late January you can glimpse both [...]
Using NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA), an international scientific team discovered that supernovae are capable of producing a substantial amount of the material from which planets like Earth can form.
These findings are published in the March 19 online issue of Science magazine.
"The dust survived the later onslaught of shock waves from the supernova explosion, and is now flowing into the interstellar medium where it can become part of the 'seed material' [...]
The International Space Station raised its orbit on Wednesday evening, placing it in the correct orientation for the docking of a new Soyuz spacecraft and crew next week. Inside the station the multinational Expedition 43 crew stayed focused on long-term microgravity studies and the upkeep of their orbital laboratory.
The ISS Progress 58 spacecraft, docked at the aft end of the Zvezda service module, fired its engines Wednesday afternoon for four minutes, 18 seconds. The orbital boost readies [...]
Lifting off from Baikonur at 01:05 am Moscow Time on Thursday, March 19, the Proton-M integrated launch vehicle (ILV) successfully orbited the Airbus DS–built Express AM-7 telecommunications satellite for Russian Satellite Communications Company (RSCC), under the Russian Federal Program, “Development of TV and Radio Broadcasting in the Russian Federation for 2009–2015”. This second launch of 2015 is the 403rd in Proton’s history.
In the course of a nominal launch, the orbital unit ( [...]
Engineers and technicians at NASA’s Johnson Space Center in Houston are testing the spacesuit astronauts will wear in the agency’s Orion spacecraft on trips to deep space. On March 17, members of the Johnson team participated in a Vacuum Pressure Integrated Suit Test to verify enhancements to the suit will meet test and design standards for the Orion spacecraft.
During this test, the suit is connected to life support systems and then air is removed from Johnson’s 11-foot thermal vacuum [...]
It's tricky to get a spacecraft to land exactly where you want. That's why the area where the Mars rover Curiosity team had targeted to land was an ellipse that may seem large, measuring 12 miles by 4 miles (20 by 7 kilometers).
Engineers at NASA's Jet Propulsion Laboratory in Pasadena, California, have been developing cutting-edge technologies that would enable spacecraft to land at a specific location on Mars -- or any other planetary body -- with more precision than ever before. In collabo [...]
On the night of March 17/18 this umbrella of northern lights unfolded over backyards in Vallentuna, Sweden about 30 kilometers north of Stockholm. A result of the strongest geomagnetic storm of this solar cycle, auroral displays were captured on that night from back and front yards at even lower latitudes, including sightings in the midwestern United States.
A boon for aurora hunting skywatchers, the space storm began building when a coronal mass ejection, launched by solar activity some two [...]
