Integral Component of Webb Space Telescope Undergoes, Survives 'Deep Freeze' Testing

From NASA: “The view from inside NASA Goddard’s Thermal Vacuum Chamber shows the JWST [James Webb Space Telescope] heart being lowered by crane in preparation of weeks of space environment testing.” An essential component of the James Webb Space Telescope has just completed and survived vacuum testing in extremely cold conditions.

Being able to find exoplanets orbiting distant stars is a major accomplishment in itself, and fine-tuning the data [...]

The universe is a wild and weird place, and two recent findings from orbiting space telescopes illustrate just how bewildering it can be: a monster-sized black hole in one of the tiniest galaxies known and a huge exoplanet that is [...]

Living On the Edge: The Inviting Waters of Europa (Part 2)

Jupiter’s moon Europa, as seen by NASA’s Galileo spacecraft. A long line of evidence has shown that Europa has an underground ocean of liquid water, which for many scientists constitutes the best place in the Solar System to search for alien life. Image Credit: NASA/JPL/Ted Stryk

Claude Nicollier—who became Switzerland’s first and so far only space traveler, the first non-U.S. [...]

Passing the Torch: Twenty-Five Years After Voyager 2, New Horizons Crosses Neptune's Orbit On Its Way to Pluto

Artist’s concept of the New Horizons spacecraft during its planned encounter with Pluto and its moon Charon in 14 July 2015. New Horizons has just completed a major milestone in its mission by crossing the orbit of Neptune on Aug. 25, exactly a quarter-of-a-century after Voyager 2 flew by the ice giant planet in [...]

Twenty-five years ago, this week, humanity braced itself for its last, first-time, close-up glimpse of a new planet in the 20th century. NASA’s Voyager 2 spacecraft, launched in [...]

Where's the Kaboom? Astronomers Detect No X-Ray Emission From Recent Supernova Explosion

The supernova SN 2014J, as imaged by NASA’s Chandra X-ray Observatory. This image contains Chandra data, where low-, medium-, and high-energy X-rays are red, green, and blue respectively. The boxes in the bottom of the image show close-up views of the region around the supernova in data taken prior to the explosion (left), as [...]

Astronomers Observe the Rhythm of Rare Type of Black Hole

Black holes can’t be observed directly, but the heated gasses surrounding them can, as they emit X-rays. Image Credit: NASA/Dana Berry/SkyWorks Digital

Black holes are one of the most unusual and fascinating phenomena in nature, and now astronomers are learning more about a peculiar type of black hole, thanks to archived data from NASA’s Rossi [...]
