Observations carried out by NASA's Swift and Nuclear Spectroscopic Telescope Array (NuSTAR) space telescopes may have located the source of intense X-ray bursts emitted by supermassive black holes. According to NASA, the phenomenon can be attributed to a component of a black hole known as a corona.
A new NASA study has suggested that gigantic spiral patterns seen around very young stars may be a telltale sign of gigantic, unseen planets in their orbit. If proved accurate, the theory would allow for a new method of planet detection, while providing an invaluable look at planet birth.
It's been a busy year for Cassini, making observations of Hyperion and Dione, before discovering evidence of a global ocean beneath the moon Enceladus' icy surface. Now the probe is back at Enceladus for another flyby, completing its deepest-ever dive through the body's icy plume.
A NASA-funded research team has confirmed the origin of organic matter found in lunar samples collected during the Apollo missions. It has long been known that the soil samples collected in the late 60s and early 70s contained amino acids, but the technology to determine where they came from has not been available until now.
NASA has analyzed 14 years worth of data collected by its Thermosphere, Inonosphere, Mesosphere Energetics and Dynamics (TIMED) satellite, revealing a surprisingly fast increase in carbon dioxide levels in the upper atmosphere. The stats also reveal that the gas is more localized to the Northern Hemisphere than predicted by climate models.
An international team of astronomers has discovered a previously unknown component of the Milky Way – a thin disk of variable stars hidden in the galactic bulge. The observations, made using the ESO's Visible and Infrared Survey Telescope for Astronomy (VISTA) telescope conflict with current theories regarding the composition of the center of our galaxy.
NASA's Dawn spacecraft has begun the process of transferring to its fourth and final mapping orbit, as it continues its mission around the dwarf planet Ceres. Dawn initially made orbit around Ceres on Mar. 6, and since then has provided us with increasingly detailed images and data, unlocking many of the mysteries harbored by the enigmatic celestial body.
A new study carried out by the Japan Aerospace Exploration Agency (JAXA) suggests that when the universe was between two to four billion years old, the elements used to create everything from the largest star to the human race were evenly spread across a vast area of the cosmos. The study focused on an enormous structure of galaxies known as the Virgo Galaxy Cluster, which sits roughly 54 million light years from Earth and harbors over 2,000 galaxies.
A new NASA study has looked at the bacteria present on the International Space Station (ISS), assessing the species that could potentially be harmful to both astronauts and equipment. The research provides useful insights that are important for long-term space flights, such as the agency's planned mission to Mars.
Astronomers have discovered large quantities of alcohol and sugar, as well as the presence of complex organic molocules, on the comet Lovejoy. The observations, made by the 30 meter (98 ft) radio telescope at Pico Veleta, Spain, support the theory that comets may have played an important role in the formation of life on Earth.
