Discovery Alert: An Earth-sized World and Its Ultra-cool Star
Our galaxy is a jewel box of red stars. More than 70% of the stars in the Milky Way are M dwarfs, also known as red dwarfs. These stars are cool and dim compared with our Sun, but they often…
Hubble Views the Dawn of a Sun-like Star
Looking like a glittering cosmic geode, a trio of dazzling stars blaze from the hollowed-out cavity of a reflection nebula in this new image from NASA’s Hubble Space Telescope. The triple-star system is made up of the variable star HP…
Hubble Celebrates the 15th Anniversary of Servicing Mission 4
Fifteen years ago, human hands touched NASA’s Hubble Space Telescope for the last time. As astronauts performed finishing tasks on the telescope during its final servicing mission in May 2009, they knew they had successfully concluded one of the most…
Hubble Glimpses a Star-Forming Factory
The celestial object showcased in this image from the NASA/ESA Hubble Space Telescope is the spiral galaxy UGC 9684, which lies around 240 million light-years from Earth in the constellation Boötes. This image shows an impressive example of several classic…
NASA Images Help Explain Eating Habits of Massive Black Hole
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…
NASA’s Webb Hints at Possible Atmosphere Surrounding Rocky Exoplanet
Researchers using NASA’s James Webb Space Telescope may have detected atmospheric gases surrounding 55 Cancri e, a hot rocky exoplanet 41 light-years from Earth. This is the best evidence to date for the existence of any rocky planet atmosphere outside…
NASA, JAXA XRISM Spots Iron Fingerprints in Nearby Active Galaxy
After starting science operations in February, Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) studied the monster black hole at the center of galaxy NGC 4151. “XRISM’s Resolve instrument captured a detailed spectrum of the area around the black hole,” said…
NASA’s TESS Returns to Science Operations
NASA’s TESS (Transiting Exoplanet Survey Satellite) returned to science operations May 3 and is once again making observations. The satellite went into safe mode April 23 following a separate period of down time earlier that month. The operations team determined…
Breaking the Scaling Limits: New Ultralow-noise Superconducting Camera for Exoplanet Searches
When imaging faint objects such as distant stars or exoplanets, capturing every last bit of light is crucial to get the most out of a scientific mission. These cameras must be extremely low-noise, and be able to detect the smallest…
How NASA’s Roman Mission Will Hunt for Primordial Black Holes
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…
