Jupiter’s Aurora Presents a Powerful Mystery

This is a reconstructed view of Jupiter’s northern lights through the filters of the Juno Ultraviolet Imaging Spectrograph instrument on Dec. 11, 2016, as the Juno spacecraft approached Jupiter, passed over its poles, and plunged towards the equator.

Intelligent alien life hunters pick up 15 high-energy bursts far across the universe

Intelligent alien life hunters pick up 15 high-energy bursts far across the universe

Instruments at the Green Bank Telescope in West Virginia identified 15 mysterious high-energy radio signals which are still unattributed. Brief but intense radio pulses have been recorded emanating from FRB 121102, a dwarf galaxy some 3 billion years away. Scientists working at Breakthrough Listen – a $100 million effort to search for alien signals – […]

Jupiter now officially has 69 moons. There are likely more to be confirmed

Jupiter now officially has 69 moons. There are likely more to be confirmed

Credit: NASA. It’s amazing how astronomers are still discussing the possibility of finding a new planet in the solar system in 2017. Compared to that, finding new moons shouldn’t be all that surprising, especially around Jupiter which is some 630 million miles away from Earth. In fact, the environment around Jupiter, a planet 317 times […]

Curiosity Peels Back Layers on Ancient Martian Lake

Curiosity Peels Back Layers on Ancient Martian Lake

This evenly layered rock imaged in 2014 by the Mastcam on NASA’s Curiosity Mars rover shows a pattern typical of a lake-floor sedimentary deposit near where flowing water entered a lake. Shallow and deep parts of an ancient Martian lake left different clues in mudstone formed from lakebed deposits. Image credit: NASA/JPL-Caltech/MSSS › Full image […]

Cassini Finds Saturn Moon May Have Tipped Over

Cassini Finds Saturn Moon May Have Tipped Over

Cassini researchers have found evidence the active south polar region of Enceladus — the fractured terrain seen here at bottom — may have originally been closer to the icy moon’s equator.

Collapsing Star Gives Birth to a Black Hole

Collapsing Star Gives Birth to a Black Hole

This illustration shows the final stages in the life of a supermassive star that fails to explode as a supernova, but instead implodes to form a black hole. Image credit: NASA/ESA/P. Jeffries (STScI) › Full image and caption › Full image and caption”/> Astronomers have watched as a massive, dying star was likely reborn as […]

Cassini Completes Final — and Fateful — Titan Flyby

Cassini Completes Final — and Fateful — Titan Flyby

NASA’s Cassini spacecraft has had its last close brush with Saturn’s hazy moon Titan and is now beginning its final set of 22 orbits around the ringed planet. The spacecraft made its 127th and final close approach to Titan on April 21 at 11:08 p.m. PDT (2:08 a.m. EDT on April 22), passing at an […]

A warp in space-time just gave us four views of one exploding star

A warp in space-time just gave us four views of one exploding star

Astronomers catch a galaxy magnifying and splitting the light from a supernova ESA/Hubble, NASA Like a lens, a galaxy (center, blue) passing in front of a supernova has split its light into four images (yellow/orange), and magnified its intensity by 52 times. Although the night sky often seems so peaceful and still, a closer look […]
