A video of magnetic field lines “slipping reconnection” bring scientists a step closer to predicting when and where large flares will occur.
The European Space Agency's (ESA) Rosetta spacecraft has caught its first glimpse of its destination comet after waking up from deep-space hibernation on January 20.
Rosetta took the "first light" images March 20 and 21 using the Optical, Spectroscopic, and Infrared Remote Imaging System (OSIRIS). These pictures are part of six weeks of activities dedicated to preparing the spacecraft’s science instruments for close-up study of comet 67P/Churyumov-Gerasimenko.
OSIRIS, developed under the l
The observation of Comet Siding Spring (C/2013 A1) should allow astronomer to measure the direction of the nucleus' pole and axis of rotation.
The discovery of dwarf galaxy black holes that are bigger than expected suggests that galaxy mergers are not necessary to create black holes.
Researchers have discovered that many white dwarfs show signs of contamination by rocky material, the leftovers from a planetary system.
This is the smallest object by far found to have rings and only the fifth body in the solar system to have this feature.
Scientists report the discovery of a distant dwarf planet, called 2012 VP113, which was found in the hypothesized inner Oort Cloud.
Curiosity is approaching a site called “the Kimberley,” where there are four types of terrain with different rock textures.
The proximity of Supernova 2014J in M82 has allowed researchers to study a type Ia supernova over a wide range of wavelengths.
Scientists and engineers are developing a prototype deployable structure, called a starshade, that would block a parent star’s light in order to better image an exoplanet.
The star-studded panorama of our galaxy is constructed from more than 2 million infrared snapshots.
If confirmed, this would be only the third binary containing both a massive star and a neutron star or black hole ever found in a supernova’s aftermath.
Images show that material flowing down from an alcove at the head of a gully broke out of an older route and eroded a new channel.
According to scientists, a rapid succession of coronal mass ejections sent a pulse of magnetized plasma barreling into space and through Earth’s orbit.
Scientists have created the largest high-resolution mosaic of our Moon’s north polar region.
Cosmic dust grains are a minor but fundamental ingredient in the recipe of gas and dust for creating stars and planets.
