Dark matter is increasingly puzzling. Around the world, physicists have been trying for decades to determine the nature of these matter particles, which do not…
This image from NASA’s Mars Reconnaissance Orbiter (MRO) shows streaks forming on slopes when dust cascades downhill. The dark streak is an area of less…
This image from NASA’s Mars Reconnaissance Orbiter (MRO) shows an impact crater looking amusingly like a tadpole because of the valley that was carved by…
Juno accomplished a close flyby over Jupiter’s churning atmosphere on Wednesday, February 7, successfully completing its tenth science orbit. The closest approach was at 6:36…
The Sun might emit less radiation by mid-century, giving planet Earth a chance to warm a bit more slowly but not halt the trend of…
Extremely distant galaxies are usually too faint to be seen, even by the largest telescopes. But nature has a solution: gravitational lensing, predicted by Albert…
Two small asteroids recently discovered by astronomers at the NASA-funded Catalina Sky Survey (CSS) near Tucson, Arizona, are safely passing by Earth within one lunar…
Magnetism plays a critical role in various solar phenomena such as flares, mass ejections, flux ropes, and coronal heating. Sunspots are areas of concentrated magnetic…
The planet Mars has long drawn interest from scientists and non-scientists as a possible place to search for evidence of life beyond Earth because the…
In the year since NASA announced the seven Earth-sized planets of the TRAPPIST-1 system, scientists have been working hard to better understand these enticing worlds…
In this view, Saturn’s icy moon Rhea passes in front of Titan as seen by NASA’s Cassini spacecraft. Some of the differences between the two…
A new study has found that the seven planets orbiting the nearby ultra-cool dwarf star TRAPPIST-1 are all made mostly of rock, and some could…
Worlds in the star’s habitable zone are not smothered under primordial atmospheres Only 40 light-years away — a stone’s throw on the scale of our…
NASA’s former chief exploration scientist, Michael Wargo, has been posthumously honored with the distinction of having a lunar crater named after him. Wargo Crater is…
Roughly 50 million light-years away lies a somewhat overlooked little galaxy named NGC 1559. Pictured here by Hubble’s Wide Field Camera 3, this barred spiral…
A University of Oklahoma astrophysics team has discovered for the first time a population of planets beyond the Milky Way galaxy. Using microlensing–an astronomical phenomenon…
A new international study involving The Australian National University (ANU) has found a plane of dwarf galaxies orbiting around Centaurus A in a discovery that…
