NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Severe weather moved through the southern U.S. on February 2nd and 3rd, and NASA’s Global Precipitation Measurement or GPM core satellite examined the violent thunderstorms.

On February 3rd, 2016 at 1851 UTC (1:51pm ET/12:51pm CT) the GPM core observatory satellite flew over a line of storms extending from the Gulf coast of Florida through New York state. Tornadoes were spotted in Georgia and South Carolina within this area of violent weather.

On Feb. 3 at 1:51 p.m. EDT GPM found that one powerful thunderstorm in North Carolina was dropping rain at the extreme rate of 112.96 mm (4.4 inches) per hour. (NASA/JAXA/SSAI, Hal Pierce)

NASA, NOAA data shows Earth’s 2015 surface temperatures were the highest in History

 

Written by Dwayne Brown
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Earth’s 2015 surface temperatures were the warmest since modern record keeping began in 1880, according to independent analyses by NASA and the National Oceanic and Atmospheric Administration (NOAA).

Globally-averaged temperatures in 2015 shattered the previous mark set in 2014 by 0.23 degrees Fahrenheit (0.13 Celsius). Only once before, in 1998, has the new record been greater than the old record by this much.

2015 was the warmest year since modern record-keeping began in 1880, according to a new analysis by NASA’s Goddard Institute for Space Studies. The record-breaking year continues a long-term warming trend — 15 of the 16 warmest years on record have now occurred since 2001. (Scientific Visualization Studio/Goddard Space Flight Center)

NASA’s Van Allen Probes data reveals new insights into Earth’s Radiation Belts

 

Written by Sarah Frazier
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – About 600 miles from Earth’s surface is the first of two donut-shaped electron swarms, known as the Van Allen Belts, or the radiation belts. Understanding the shape and size of the belts, which can shrink and swell in response to incoming radiation from the sun, is crucial for protecting our technology in space.

The harsh radiation isn’t good for satellites’ health, so scientists wish to know just which orbits could be jeopardized in different situations.

NASA Space Telescopes and Observatories study Young Galaxy Cluster in detail

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Astronomers have used data from three of NASA’s Great Observatories to make the most detailed study yet of an extremely massive young galaxy cluster. This rare cluster, which is located 10 billion light-years from Earth, weighs as much as 500 trillion suns. This object has important implications for understanding how these megastructures formed and evolved early in the universe.

The galaxy cluster, called IDCS J1426.5+3508 (IDCS 1426 for short), is so far away that the light detected is from when the universe was roughly a quarter of its current age. It is the most massive galaxy cluster detected at such an early age.

NASA’s Spitzer and Hubble space telescopes discovers two massive stars in Eta Carinae system

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Eta Carinae, the most luminous and massive stellar system within 10,000 light-years of Earth, is best known for an enormous eruption seen in the mid-19th century that hurled at least 10 times the sun’s mass into space.

This expanding veil of gas and dust , which still shrouds Eta Carinae, makes it the only object of its kind known in our galaxy. Now a study using archival data from NASA’s Spitzer and Hubble space telescopes has found five objects with similar properties in other galaxies for the first time.

Hubble view of M83 -- the only galaxy known to host two potential "Eta twins." Its high rate of star formation increases the chances of finding massive stars that have recently undergone an Eta Carinae-like outburst. Bottom: Hubble data showing the locations of M83's Eta twins.

NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) observes Andromeda Galaxy in X-Ray Vision

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Nuclear Spectroscopic Telescope Array, or NuSTAR, has captured the best high-energy X-ray view yet of a portion of our nearest large, neighboring galaxy, Andromeda. The space mission has observed 40 “X-ray binaries” — intense sources of X-rays comprised of a black hole or neutron star that feeds off a stellar companion.

The results will ultimately help researchers better understand the role of X-ray binaries in the evolution of our universe. According to astronomers, these energetic objects may play a critical role in heating the intergalactic bath of gas in which the very first galaxies formed.

NASA observes Extreme Weather across United States

 

Written by Hal Pierce / Rob Gutro
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA’s Global Precipitation Measurement or GPM mission core satellite analyzed extreme weather that affected the U.S. over the course of five days. Heavy rainfall, flooding and tornado outbreaks affected areas of the United States from the Southwest through the Midwest from December 23rd to 27th, 2015.

GPM is an international satellite mission between NASA and the Japan Aerospace Exploration Agency to provide next-generation observations of rain and snow worldwide every three hours.

NASA reports Euclid Mission to investigate mysteries of Dark Matter and Dark Energy

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Euclid, a planned mission to investigate the profound cosmic mysteries of dark matter and dark energy, has passed its preliminary design review. This clears the way for construction to begin.

Euclid is a European Space Agency mission with important contributions from NASA, including infrared detectors for one instrument and science and data analysis.

Euclid is designed to give us important new insights into the “dark side” of the universe — namely dark matter and dark energy, both thought to be key components of our cosmos.

NASA reports Christmas Day Full Moon

 

Written by Nancy Neal Jones
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – Not since 1977 has a full moon dawned in the skies on Christmas. But this year, a bright full moon will be an added gift for the holidays.

December’s full moon, the last of the year, is called the Full Cold Moon because it occurs during the beginning of winter. The moon’s peak this year will occur at 5:11am CST.

This rare event won’t happen again until 2034. That’s a long time to wait, so make sure to look up to the skies on Christmas Day.

NASA studies how 2015 El Niño effects the World’s Climate

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – People the world over are feeling, or will soon feel, the effects of the strongest El Niño event since 1997-98, currently unfolding in the eastern equatorial Pacific Ocean. New NASA satellite observations are beginning to show scientists its impact on the distribution of rain, tropospheric ozone and wildfires around the globe.

New results presented Tuesday, December 15th, at the American Geophysical Union meeting in San Francisco show that atmospheric rivers, significant sources of rainfall, tend to intensify during El Niño events, and this year’s strong El Niño likely will bring more precipitation to California and some relief for the drought.
