NASA astronaut Christina Koch set record for longest single Spaceflight by any Woman

February 5, 2020 |

Washington, D.C. – NASA astronaut Christina Koch is set to return to Earth on Thursday, February 6th, 2020 after 328 days living and working aboard the International Space Station. Her mission is the longest single spaceflight by any woman, which is helping scientists gather data for future missions to the Moon and Mars.

Koch will return to Earth alongside ESA (European Space Agency) astronaut Luca Parmitano and Russian cosmonaut Alexander Skvortsov. She has been a crew member for three expeditions – 59, 60 and 61 – during her first spaceflight.

Astronomers observe Red Giant destroying one of it’s Planets, Could our Sun do the same to the Earth

Washington, D.C. – An international team of astronomers has caught a star in the act of devouring one of its planets. BD+48 740, a red giant they observed using the 9.2-meter Hobby-Eberly Telescope at the McDonald Observatory in Texas, appears to have the fumes of a scorched planet in its atmosphere. This is consistent with a rocky world, recently destroyed.

Could the same thing happen to Earth?

Yes indeed, says Alex Wolszczan, a member of the research team from Penn State University: “A similar fate may await the inner planets in our solar system when the sun becomes a red giant some five billion years from now.”

NASA to study active volcanoes in Alaska and Japan using images from it’s Uninhabited Aerial Vehicle Synthetic Aperture Radar

Edwards, CA – A NASA aircraft carrying a unique 3-D aerial radar developed by NASA’s Jet Propulsion Laboratory, Pasadena, CA, has left California for a 10-day campaign to study active volcanoes in Alaska and Japan.

The modified NASA C-20A (G-III) aircraft, with JPL’s Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) installed in a pod under its belly, departed NASA’s Dryden Aircraft Operations Facility in Palmdale, CA, October 2nd, en route to Joint Base Lewis-McChord in Tacoma, WA.

This UAVSAR interferogram shows active volcano Mount St. Helens (left) and dormant volcano Mount Adams, both in Washington state. The sensor collected data for this image during flights in July 2009 and August 2010 to compute the surface deformation that could indicate activity in the volcanoes’ magma. No deformation was evident during this period. (NASA image)

Re-thinking an Alien World

Washington, D.C. – Forty light years from Earth, a rocky world named “55 Cancri e” circles perilously close to a stellar inferno.  Completing one orbit in only 18 hours, the alien planet is 26 times closer to its parent star than Mercury is to the Sun. If Earth were in the same position, the soil beneath our feet would heat up to about 3200 F.  Researchers have long thought that 55 Cancri e must be a wasteland of parched rock.

Now they’re thinking again.  New observations by NASA’s Spitzer Space Telescope suggest that 55 Cancri e may be wetter and weirder than anyone imagined.

An artist's concept of Earth and 55 Cancri e positioned side by side for comparison.

Discovered: Stars as Cool as the Human Body

August 25, 2011 |

Washington, D.C. – Scientists using data from NASA’s Wide-field Infrared Survey Explorer (WISE) have discovered six “Y dwarfs”– star-like bodies with temperatures as cool as the human body.

Astronomers hunted these dark orbs for more than a decade without success. When viewed with a visible-light telescope, they are nearly impossible to see. WISE’s infrared vision allowed the telescope to finally spot the faint glow of a half dozen Y dwarfs relatively close to our sun, within a distance of about 40 light-years.

This artist's conception illustrates what a "Y dwarf" might look like. Y dwarfs are the coldest star-like bodies known, with temperatures that can be even cooler than the human body. (Photo by NASA/JPL-Caltech)
