NASA's Fermi Helps Link Cosmic Neutrino to Blazar Blast

Nearly 10 billion years ago, the black hole at the center of a galaxy known as PKS B1424-418 produced a powerful outburst. Light from this blast began arriving at Earth in 2012. Now astronomers using data from NASA’s Fermi Gamma-ray Space Telescope have shown that a record-breaking neutrino seen around the same time likely was […]

Spitzer Uses Light Echoes to Give Clues to Protoplanetary Disk

Using data from NASA’s Spitzer Space Telescope and four ground-based telescopes, astronomers determine the distance from a star to the inner rim of its surrounding protoplanetary disk. Imagine you want to measure the size of a room, but it’s completely dark. If you shout, you can tell if the space you’re in is relatively big […]

Hubble Views NGC 4111

This newly released Hubble image shows lenticular galaxy NGC 4111. The elegant simplicity of NGC 4111, seen here in this image from the NASA/ESA Hubble Space Telescope, hides a more violent history than you might think. NGC 4111 is a lenticular, or lens-shaped, galaxy, lying about 50 million light-years from us in the constellation of […]

New Research Shows Pluto’s Haze Varies in Brightness

New images from NASA’s New Horizons Spacecraft reveal that Pluto’s haze varies in brightness. Scientists on NASA’s New Horizons mission team are learning more about the structure and behavior of Pluto’s complex atmosphere by discovering new attributes of its extensive haze layers. The hazes were first discovered by New Horizons in July, as the spacecraft […]

NASA Reports Cassini Spacecraft Not Affected by Hypothetical Planet 9

According to mission managers and orbit determination experts at NASA’s Jet Propulsion Laboratory, the Cassini Spacecraft is not experiencing unexplained deviations in its orbit around Saturn. Several recent news stories have reported that a mysterious anomaly in Cassini’s orbit could potentially be explained by the gravitational tug of a theorized massive new planet in our […]

New Image of Saturn from Cassini

Another great image of Saturn from NASA’s Cassini Spacecraft. As a convention for public release, Cassini images of Saturn are generally oriented so that Saturn appears north up, but the spacecraft views the planet and its expansive rings from all sorts of angles. Here, a half-lit Saturn sits askew as tiny Dione (698 miles or […]

Chandra Reveals Jupiter’s Northern Lights

Using data from NASA’s Chandra X-Ray Observatory, astronomers show that solar storms trigger Jupiter’s intense ‘Northern Lights’ by generating a new X-ray aurora that is eight times brighter than normal and hundreds of times more energetic than Earth’s aurora borealis. It is the first time that Jupiter’s X-ray aurora has been studied when a giant […]
