Image of Neptune from Voyager 2

This historic image of Neptune was taken twenty-five years ago by NASA’s Voyager 2 Spacecraft. NASA’s Voyager 2 spacecraft gave humanity its first glimpse of Neptune and its moon Triton in the summer of 1989. This picture of Neptune was produced from the last whole planet images taken through the green and orange filters on […]

NASA Detects Best Evidence Yet For Coronal Heating Theory

NASA’s EUNIS sounding rocket mission has discovered evidence to explain why the sun’s atmosphere is so much hotter than its surface, detecting the strongest evidence yet for the presence of nanoflares. Scientists have recently gathered some of the strongest evidence to date to explain what makes the sun’s outer atmosphere so much hotter than its […]

Cassini Reveals 101 Geysers on Enceladus

Using data from NASA’s Cassini spacecraft, two newly published studies detail the discovery of 101 distinct geysers on Saturn’s icy moon Enceladus. Scientists using mission data from NASA’s Cassini spacecraft have identified 101 distinct geysers erupting on Saturn’s icy moon Enceladus. Their analysis suggests it is possible for liquid water to reach from the moon’s […]

New Views of the Rosetta Comet

New images from ESA’s Rosetta spacecraft reveal surface structures of comet 67P/Churyumov-Gerasimenko, allowing scientists to create a 3D shape model of the nucleus. As the European Space Agency’s Rosetta probe approaches Comet 67P/Churyumov-Gerasimenko (67P) for an August rendezvous, the comet’s core is coming into sharper focus. Today, ESA released a new set of images and […]

Pulsar Switched from Radio Emissions to High Energy Gamma Rays

New measurements by NASA’s Fermi Gamma-ray Space Telescope reveal a binary star system whose pulsar switched from radio emissions to high-energy gamma rays. Zoom into an artist’s concept of AY Sextantis, a binary star system whose pulsar switched from radio emissions to high-energy gamma rays in 2013. This transition likely means the pulsar’s spin-up process […]
