Nearly a decade ago, NASA's Chandra X-ray Observatory caught signs of what appeared to be a black hole snacking on gas at the middle of the nearby Sculptor galaxy. Now, NASA's Nuclear Spectroscopic Telescope Array (NuSTAR), which sees higher-energy X-ray light, has taken a peek and found the black hole asleep.
As part of an international team of exoplanets hunters, astronomers at the University of Arizona are developing a technique to detect faint dust clouds around other stars, many of which might hide Earth-like planets.
Based on a treasure trove of recent discoveries, astronomers now know that planets are remarkably plentiful in our galaxy and may be common throughout the Universe. Though planets appear to form readily, the actual process of planet formation remains a mystery and astronomers are searching for the missing pieces to this cosmic puzzle.
By comparing infrared and X-ray background signals across the same stretch of sky, an international team of astronomers has discovered evidence of a significant number of black holes that accompanied the first stars in the universe.
Astronomers at NASA and Pennsylvania State University have used NASA's Swift satellite to create the most detailed ultraviolet light surveys ever of the Large and Small Magellanic Clouds, the two closest major galaxies.
Nine years after ESO's Very Large Telescope captured the first image of an exoplanet, the planetary companion to the brown dwarf 2M1207, the same team has caught on camera what is probably the lightest of these objects so far.
In preparation for a future where parts and tools can be printed on demand in space, NASA and Made in Space Inc. have joined to launch equipment for the first 3-D microgravity printing experiment to the International Space Station.
With data from NASA's twin spacecraft, STEREO, researchers developed a novel technique, called geometric triangulation, which can determine the trajectory and velocity of coronal mass ejections continuously when they travel in interplanetary space.
Conventional research on distant galaxies have been carried out mainly with visible light and near infrared light. However, it is possible that many galaxies in the universe have been overlooked as much of that radiation is largely absorbed by cosmic dust.
