Astronomers Find Planet Hotter Than Most Stars

Astronomers Find Planet Hotter Than Most Stars

This artist’s concept shows planet KELT-9b orbiting its host star, KELT-9. It is the hottest gas giant planet discovered so far.

With a dayside temperature of more than […]

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 […]

NASA: New Insights into ‘Ocean Worlds’ in Our Solar System

NASA: New Insights into ‘Ocean Worlds’ in Our Solar System

Two veteran NASA missions are providing new details about icy, ocean-bearing moons of Jupiter and Saturn, further heightening the scientific interest of these and other “ocean worlds” in our solar system and beyond. The findings are presented in papers published Thursday by researchers with NASA’s Cassini mission to Saturn and Hubble Space Telescope. In the […]

NASA’s Cassini Mission Prepares for ‘Grand Finale’ at Saturn

NASA’s Cassini Mission Prepares for ‘Grand Finale’ at Saturn

NASA’s Cassini spacecraft, in orbit around Saturn since 2004, is about to begin the final chapter of its remarkable story. On Wednesday, April 26, the spacecraft will make the first in a series of dives through the 1,500-mile-wide (2,400-kilometer) gap between Saturn and its rings as part of the mission’s grand finale. “No spacecraft has […]

Earth Science on the Space Station Continues to Grow

Earth Science on the Space Station Continues to Grow

The number of instruments on the International Space Station dedicated to observing Earth to increase our understanding of our home planet continues to grow. Two new instruments are scheduled to make their way to the station Feb. 18 on the SpaceX Dragon capsule. The Stratospheric Aerosol and Gas Experiment (SAGE) III instrument will monitor the […]

Black Holes Hide in Our Cosmic Backyard

Black Holes Hide in Our Cosmic Backyard

Monster black holes sometimes lurk behind gas and dust, hiding from the gaze of most telescopes. But they give themselves away when material they feed on emits high-energy X-rays that NASA’s NuSTAR (Nuclear Spectroscopic Telescope Array) mission can detect. That’s how NuSTAR recently identified two gas-enshrouded supermassive black holes, located at the centers of nearby […]
