NASA’s TESS Finds Intriguing World Sized Between Earth, Venus – NASA Science

5 min read NASA’s Compact Infrared Cameras Enable New Science A new, higher-resolution infrared camera outfitted with a variety of lightweight filters could probe sunlight reflected off Earth’s upper atmosphere and surface, improve forest fire warnings, and reveal the molecular composition of other planets. The cameras use sensitive, high-resolution strained-layer superlattice sensors, initially developed at … Read more

Spotted: ‘Death Star’ Black Holes in Action – NASA

Spotted: ‘Death Star’ Black Holes in Action – NASA

A team of astronomers have studied 16 supermassive black holes that are firing powerful beams into space, to track where these beams, or jets, are pointing now and where they were aimed in the past, as reported in our latest press release. Using NASA’s Chandra X-ray Observatory and the U.S. National Science Foundation (NSF) National Radio Astronomical Observatory’s (NRAO) Very … Read more

NASA Images Help Explain Eating Habits of Massive Black Hole – NASA

Data from NASA’s retired Spitzer Space Telescope has given scientists new insights into why some supermassive black holes shine differently than others. In images from NASA’s retired Spitzer Space Telescope, streams of dust thousands of light-years long flow toward the supermassive black hole at the heart of the Andromeda galaxy. It turns out these streams … Read more

NASA’s Chandra Notices the Galactic Center is Venting – NASA

These images show evidence for an exhaust vent attached to a chimney releasing hot gas from a region around the supermassive black hole at the center of the Milky Way, as reported in our latest press release. In the main image of this graphic, X-rays from NASA’s Chandra X-ray Observatory (blue) have been combined with radio data from the MeerKAT telescope (red). Previously, astronomers had … Read more

How NASA’s Roman Mission Will Hunt for Primordial Black Holes – NASA

Astronomers have discovered black holes ranging from a few times the Sun’s mass to tens of billions. Now a group of scientists has predicted that NASA’s Nancy Grace Roman Space Telescope could find a class of “featherweight” black holes that has so far eluded detection. Today, black holes form either when a massive star collapses … Read more

Hubble Spots a Magnificent Barred Galaxy – NASA

The magnificent central bar of NGC 2217 (also known as AM 0619-271) shines bright in the constellation of Canis Major (The Greater Dog), in this image taken by the NASA/ESA Hubble Space Telescope. Roughly 65 million light-years from Earth, this barred spiral galaxy is a similar size to our Milky Way at 100,000 light-years across. Many stars are concentrated in its … Read more

A Solar Neighborhood Census, Thanks to NASA Citizen Science

A Solar Neighborhood Census, Thanks to NASA Citizen Science

A small team of citizen scientists developed a tool called WISE View, using images from NASA’s WISE (Wide-Field Infrared Survey Explorer) mission, to easily stitch together images into animations. A larger group of volunteers then used those animations to find moving objects. “They’ve made the project more efficient for everyone else,” Kirkpatrick said. (WISE’s mission … Read more

How NASA’s Roman Telescope Will Measure Ages of Stars – NASA

Guessing your age might be a popular carnival game, but for astronomers it’s a real challenge to determine the ages of stars. Once a star like our Sun has settled into steady nuclear fusion, or the mature phase of its life, it changes little for billions of years. One exception to that rule is the … Read more

NASA’s Webb Probes an Extreme Starburst Galaxy

NASA’s Webb Probes an Extreme Starburst Galaxy

On the left is the starburst galaxy M82 as observed by NASA’s Hubble Space Telescope in 2006. The small box at the galaxy’s core corresponds to the area captured so far by the NIRCam (Near-Infrared Camera) instrument on NASA’s James Webb Space Telescope. The red filaments as seen by Webb are the polycyclic aromatic hydrocarbon … Read more
