A team of scientists including a University of Colorado Boulder professor used NASA's Hubble Space Telescope to make the most detailed global map yet of the glow from a giant, oddball planet orbiting another star, an object twice as massive as Jupiter and hot enough to melt steel.

A supernova is the cataclysmic death of a star, but it seems its remnants shine on. Astronomers have found a pulsating, dead star beaming with the energy of about 10 million suns.
This is the brightest pulsar -- a dense stellar remnant leftover from a supernova -- ever recorded, and was seen using NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR.
Lawrence Livermore LLNL researchers were involved in the design and testing of the NuSTAR X-ray optics.
NASA's Aqua satellite passed over Super Typhoon Vongfong as it tracked through the Philippine Sea on Oct. 9. Instrument aboard Aqua captured visible and infrared images of the now Category 4 Super Typhoon.
NASA's Aqua satellite flew over Tropical Cyclone Hudhud on Oct. 9 and took a picture of the storm that showed it was still somewhat elongated, but more organized than the previous day. Another NASA satellite provided the hint of a developing eye. Warnings for winds, rain and surf are already in effect for the northern Andhra Pradesh coast and south Odisha coastline of eastern India as Hudhud approaches.
Tropical Cyclone Hudhud formed on Oct. 8 and began moving from east to west across the Bay of Bengal, Northern Indian Ocean.
Following her husband Franklin D. Roosevelt's death in April 1945, Eleanor Roosevelt was freed from the constraints of the White House and eagerly expanded her career. She used radio to communicate on a wide variety of issues and became a radio pioneer, broadcasting from the 1920s, starting with her own radio show in 1932. She spoke on US domestic radio, the BBC, Voice of America, on French radio (in French) and Italian radio (in Italian). She was also interviewed in Spanish and German. In 1948 she hosted a twice weekly radio program with her daughter Anna on ABC.
ITHACA, N.Y. – A little known secret in data mining is that simply feeding raw data into a data analysis algorithm is unlikely to produce meaningful results, say the authors of a new Cornell University study.
A new measurement of dark matter in the Milky Way has revealed there is half as much of the mysterious substance as previously thought.
Australian astronomers used a method developed almost 100 years ago to discover that the weight of dark matter in our own galaxy is 800 000 000 000 (or 8 x 1011) times the mass of the Sun.
They probed the edge of the Milky Way, looking closely, for the first time, at the fringes of the galaxy about 5 million billion kilometres from Earth.
It has been known for several years that sulfuric acid contributes to the formation of tiny aerosol particles, which play an important role in the formation of clouds. The new study by Kürten et al. shows that dimethylamine can tremendously enhance new particle formation. The formation of neutral (i.e. uncharged) nucleating clusters of sulfuric acid and dimethylamine was observed for the first time.
When a woman is in labour, the appropriate time to give an epidural during childbirth is when she asks for it, a new study suggests. Published in The Cochrane Library, the systematic review compared early and late epidurals during labour and found that they had very similar effects.
Hurricane Simon appeared to be keeping a secret before it rapidly intensified on Oct. 4, but the Global Precipitation Measurement or GPM satellite was able uncover it.
On Oct. 4 at 0940 UTC (5:40 a.m. EDT) observations by the Ku-band radar on the GPM satellite suggested that the Eastern Pacific Ocean's Hurricane Simon was hiding a very compact eyewall hours before the National Hurricane Center detected rapid intensification of Simon's surface winds. The GPM satellite was launched in February of this year and is managed by both NASA and the Japan Aerospace Exploration Agency.
Gamma rays are the highest-energy form of radioactive waves known in the universe. However, how they're made and where they come from have been a bit of a mystery.
But now a team of researchers, led by Michigan State University astronomer Laura Chomiuk, has made a discovery that may shed some light on the subject.
Using highly detailed radio telescope images, Chomiuk and her team have pinpointed the location where an explosion on the surface of a star, known as a nova, emitted gamma rays.
This, said Chomiuk, is something they did not expect to encounter.
The Northern Indian Ocean has awakened after a tropical slumber and created Tropical Storm Hudhud on Oct. 8 and NASA's Aqua satellite passed overhead.
The Atmospheric Infrared Sounder or AIRS instrument that flies aboard NASA's Aqua satellite passed over Tropical Cyclone Hudhud on Oct. 8 at 6:53 UTC (2:53 a.m. EDT and captured infrared data on the storm revealing bands of strong thunderstorms around the center.
Astronomers working with NASA's Nuclear Spectroscopic Telescope Array (NuSTAR), led by Caltech's Fiona Harrison, have found a pulsating dead star beaming with the energy of about 10 million suns. The object, previously thought to be a black hole because it is so powerful, is in fact a pulsar—the incredibly dense rotating remains of a star.
Two NASA satellites provided data on clouds, rainfall and the diameter of the eye of Super Typhoon Vongfong as it turned north in the Northwestern Pacific Ocean.
Typhoon Vongfong formed on October 2, 2014 southeast of Guam. Typhoon Phanfone, that recently pummeled Japan, formed near the same area in the western Pacific Ocean.
Plant scientists are working to improve important food crops such as rice, maize, and beans to meet the food needs of a growing world population. However, boosting crop output will require improving more than what can be seen of these plants above the ground. Root systems are essential to gathering water and nutrients, but understanding what's happening in these unseen parts of the plants has until now depended mostly on lab studies and subjective field measurements.
