These misaligned features seem to defy conventional thinking about the saturnian moon’s windy atmosphere, which should quickly smear out such off-axis concentrations.
Research provides new evidence that it is jets of “radio-frequency feedback” streaming from mature galaxies’ central black holes that prevent hot free gas from cooling and collapsing into baby stars.
The HARPS instrument has been used to make the most complete census of comets around another star ever created.
Observations of these high-energy eruptions provide information on how the neutron star’s surface twists and vibrates.
The detection is a sign that this cosmic light has been warped by intervening structures in the universe.
The data provide new insights into what drives the rise in temperature from the Sun’s surface to its outer atmosphere.
This new detection is considered one of the most reliable distance measurements of a galaxy that existed in the early universe.
The data suggest that something is not right inside Mimas; the amount of wobble measured is double what was predicted.
The Mars Reconnaissance Orbiter, MAVEN, and Mars Odyssey all are part of a campaign to study Comet Siding Spring and possible effects on the martian atmosphere from gases and dust released by the comet.
The images indicate that Mercury’s polar deposits either were delivered to the planet recently or are regularly restored at the surface through an ongoing process.
The study showed that star formation in the Spiderweb Cluster is concentrated mostly in a single region, not on the large filaments connecting galaxies as expected.
This was a needle-in-haystack search because the elusive objects are extremely small, faint, and difficult to pick out against myriad background stars.
The first data includes information on energetic solar particles that reach Mars and the oxygen, hydrogen, and carbon coronas surround the Red Planet.
Scientists have detected small lumps within the smooth scattering disk of the Milky Way's supermassive black hole.
Astronomers made the measurement by studying the speed of stars throughout the galaxy, including the edges, which had never been studied to this detail before.
The new information is hard to reconcile with what scientists currently think about the temperature of the interior of the Moon.
A team of scientists has made the most detailed global map yet of the glow from a turbulent planet, WASP-43b, outside our solar system.
Comet Siding Spring will pass within about 87,000 miles (139,500 kilometers) of the Red Planet on October 19.
The Rosetta spacecraft’s images of grooves found the asteroid point to the existence of a large impact crater on the unseen side of the rocky world.
The discovery revealed a probable mechanism for the gamma-ray emissions, which mystified astronomers when first observed in 2012.
