The Jupiter-size object, called WD 1856 b, is about seven times larger than the white dwarf, named WD 1856+534. It circles this stellar cinder every 34 hours, more than 60 times faster than Mercury orbits our Sun. ![]() WD 1856 b, a potential planet the size of Jupiter, orbits its dim white dwarf star every 36 hours and is about seven times larger.

NASA’s Transiting Exoplanet Survey Satellite (TESS) discovers Earth size planet within Habitable Zone
TOI 700 d is one of only a few Earth-size planets discovered in a star’s habitable zone so far. Others include several planets in the TRAPPIST-1 system and other worlds discovered by NASA’s Kepler Space Telescope. ![]() TOI 700, a planetary system 100 light-years away in the constellation Dorado, is home to TOI 700 d, the first Earth-size habitable-zone planet discovered by NASA’s Transiting Exoplanet Survey Satellite.

NASA’s Chandra X-ray Observatory discovers stars kicked from their Galaxies
Astronomers use the term “binary” system to refer to pairs of stars orbiting around each other. These stellar pairs can consist of combinations of stars like our Sun, or more exotic and denser varieties such as neutron stars or even black holes. «Read the rest of this article» Sections: Technology | No Comments
NASA’s Juno spacecraft discovers Changes in Magnetic Field of Jupiter
The discovery will help scientists further understand Jupiter’s interior structure – including atmospheric dynamics – as well as changes in Earth’s magnetic field. A paper on the discovery was published today in the journal Nature Astronomy. ![]() This still from an animation illustrates Jupiter’s magnetic field at a single moment in time. The Great Blue Spot, an-invisible-to-the-eye concentration of magnetic field near the equator, stands out as a particularly strong feature.

NASA lists 10 Things You Should Know About Planetary DefenseNASA Headquarters
NASA says these objects orbit the Sun just like the planets, as they have been doing for billions of years, but small effects such as gravitational nudges from the planets can jostle the orbits, making them gradually shift over million-year timescales or abruptly reposition if there is a close planetary encounter. ![]() These three radar images of near-Earth asteroid 2003 SD220 were obtained on Dec. 15-17, by coordinating observations with NASA’s 230-foot (70-meter) antenna at the Goldstone Deep Space Communications Complex in California and the National Science Foundation’s (NSF) 330-foot (100-meter) Green Bank Telescope in West Virginia.

NASA’s Chandra X-ray Observatory studies Cosmic Cold Front in Perseus GalaxyNASA Marshall Space Flight Center
The researchers used NASA’s Chandra X-ray Observatory to study a cold front located in the Perseus galaxy cluster that extends for about two million light years, or about 10 billion billion miles. Galaxy clusters are the largest and most massive objects in the Universe that are held together by gravity. In between the hundreds or even thousands of galaxies in a cluster, there are vast reservoirs of super-heated gas that glow brightly in X-ray light. ![]() A gigantic and resilient “cold front” hurtling through the Perseus galaxy cluster has been studied using data from NASA’s Chandra X-ray Observatory.

NASA and NOAA study shows warmer weather increasing Carbon Emissions from Alaska TundraWritten by Ellen Gray
More carbon dioxide released to the atmosphere will accelerate climate warming, which, in turn, could lead to the release of even more carbon dioxide from these soils. A new paper led by Roisin Commane, an atmospheric researcher at Harvard University in Cambridge, Massachusetts, finds the amount of carbon dioxide emitted from northern tundra areas between October and December each year has increased 70 percent since 1975. ![]() Winter sun setting over the tundra polygons in northern Alaska in November 2015. As winter sets in and snow settles, the soils take time to freeze completely and continue to emit carbon dioxide long into the new year.

NASA Study suggests decreased Hydroxyl levels maybe the cause of recent Methane increasesWritten by Alan Buis
The second most important human-produced greenhouse gas after carbon dioxide, methane is colorless, odorless and can be hard to track. The gas has a wide range of sources, from decomposing biological material to leaks in natural gas pipelines. ![]() Rice paddy fields in India. Agriculture is one source of global methane emissions.

NASA’s Chandra X-ray Observatory studies Comet ISON and Comet PanSTARRSWritten by Molly Porter
While comets are inherently interesting, they can also provide information about other aspects of our Solar System. More specifically, comets can be used as laboratories to study the behavior of the stream of particles flowing away from the Sun, known as the solar wind. Recently, astronomers announced the results of a study using data collected with NASA’s Chandra X-ray Observatory of two comets — C/2012 S1 (also known as “Comet ISON”) and C/2011 S4 (“Comet PanSTARRS”). ![]() The Comets ISON and PanSTARRS in optical images taken by an astrophotographer, with insets showing the X-ray images from Chandra.

NASA’s Chandra X-ray Observatory finds far away Supermassive Black HoleWritten by Molly Porter
The light detected from this jet was emitted when the Universe was only 2.7 billion years old, a fifth of its present age. At this point, the intensity of the cosmic microwave background radiation, or CMB, left over from the Big Bang was much greater than it is today. ![]() Extended X-ray jet associated with quasar B3 0727+409.
