NASA says network of Telescopes captures historic Black Hole image

April 11, 2019 |

NASA Headquarters

Washington, D.C. – A black hole and its shadow have been captured in an image for the first time, a historic feat by an international network of radio telescopes called the Event Horizon Telescope (EHT). EHT is an international collaboration whose support in the U.S. includes the National Science Foundation.

A black hole is an extremely dense object from which no light can escape. Anything that comes within a black hole’s “event horizon,” its point of no return, will be consumed, never to re-emerge, because of the black hole’s unimaginably strong gravity.

Scientists have obtained the first image of a black hole, using Event Horizon Telescope observations of the center of the galaxy M87. The image shows a bright ring formed as light bends in the intense gravity around a black hole that is 6.5 billion times more massive than the Sun. (Event Horizon Telescope Collaboration)

NASA reports Wintertime Arctic Sea Ice Growth Slows, Long-term Decline

December 10, 2018 |

Written by Maria-José Viñas
NASA’s Earth Science News Team

Washington, D.C. – New NASA research has found that increases in the rate at which Arctic sea ice grows in the winter may have partially slowed down the decline of the Arctic sea ice cover.

As temperatures in the Arctic have warmed at double the pace of the rest of the planet, the expanse of frozen seawater that blankets the Arctic Ocean and neighboring seas has shrunk and thinned over the past three decades. The end-of-summer Arctic sea ice extent has almost halved since the early 1980s. A recent NASA study found that since 1958, the Arctic sea ice cover has lost on average around two-thirds of its thickness and now 70 percent of the sea ice cap is made of seasonal ice, or ice that forms and melts within a single year.

NASA reports Astronomers observe Supermassive Black Hole devour a Star

June 16, 2018 |

NASA’s Jet Propulsion Laboratory

Pasadena, CA – For the first time, astronomers have directly imaged the formation and expansion of a fast-moving jet of material ejected when the powerful gravity of a supermassive black hole ripped apart a star that wandered too close to the massive monster.

The scientists tracked the event with radio and infrared telescopes, including the National Science Foundation’s Very Long Baseline Array (VLBA) and NASA’s Spitzer Space Telescope, in a pair of colliding galaxies called Arp 299.

NASA collects Meteorites in Antarctica

Greenbelt, MD – On rare calm days, the most striking thing you notice at an altitude of more than 8,000 feet on an Antarctic glacier is the silence.

“There was just no sound; no air handling equipment, no leaves rustling, no bugs, no planes or cars. So quiet you just heard your heartbeat,” said Barbara Cohen, planetary scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. Most of the time, however, there is a steady howl of bitter cold wind flowing down from the East Antarctic ice plateau. With a summer temperature hovering around zero Fahrenheit, “It’s the wind that makes you cold,” Cohen said.

NASA’s Space Communications Networks turns 20

NASA’s Goddard Space Flight Center

Greenbelt, MD –  NASA’s Tracking and Data Relay Satellites (TDRS) don’t just enable data from spacecraft to reach Earth – they provide internet and even telemedicine to researchers at the South Pole. The South Pole TDRS Relay (SPTR) system turns 20 years old on January 9th, 2018.

In the 1990s, the National Science Foundation (NSF) faced a communications challenge with more than a hundred scientists working at their Amundsen-Scott South Pole Station in Antarctica per year to study everything from meteorology to astrophysics to climate.

The South Pole TDRS Relay (SPTR) ground terminal was installed at the National Science Foundation’s Amundsen-Scott South Pole Station in December 1997 to help connect NSF researchers and their scientific data to the rest of the world. This image shows the original SPTR system, which became operational on Jan. 9, 1998. (NASA)

NASA’s Hubble and Spitzer space telescopes observe Dying Star reborn into a Black Hole

Written by Elizabeth Landau

Pasadena, CA – Astronomers have watched as a massive, dying star was likely reborn as a black hole. It took the combined power of the Large Binocular Telescope (LBT), and NASA’s Hubble and Spitzer space telescopes to go looking for remnants of the vanquished star, only to find that it disappeared out of sight.

It went out with a whimper instead of a bang.

The star, which was 25 times as massive as our sun, should have exploded in a very bright supernova. Instead, it fizzled out — and then left behind a black hole.

This illustration shows the final stages in the life of a supermassive star that fails to explode as a supernova, but instead implodes to form a black hole. (NASA/ESA/P. Jeffries (STScI))

NASA study reveals new method of Ice Loss in Greenland

May 26, 2017 |

Written by Carol Rasmussen
NASA Earth Science News Team

Washington, D.C. – A new NASA study finds that during Greenland’s hottest summers on record, 2010 and 2012, the ice in Rink Glacier on the island’s west coast didn’t just melt faster than usual, it slid through the glacier’s interior in a gigantic wave, like a warmed freezer pop sliding out of its plastic casing.

The wave persisted for four months, with ice from upstream continuing to move down to replace the missing mass for at least four more months.

This long pulse of mass loss, called a solitary wave, is a new discovery that may increase the potential for sustained ice loss in Greenland as the climate continues to warm, with implications for the future rate of sea level rise.
