NASA Scientist to Discuss “Space Lasers and Satellite Measurements” at Library of Congress Lecture

Tue, 11/26/2019 - 08:54
The public is invited to a free lecture titled “Space Lasers and Satellite Measurements: Ushering in a New Era of Spaceborne Laser Altimetry Dependent on Satellite Geodesy."

NASA Embarks on Five U.S. Expeditions Targeting Air, Land and Sea

Tue, 11/26/2019 - 08:31
NASA is sending five campaigns across the United States to investigatefundamental processes that ultimately impact human lives and the environment.

'The Invisible Network' Podcast - Episode 09: Lobes

Mon, 11/25/2019 - 10:47
Spacecraft near Earth have long relied on GPS signals for navigation, just as users on the ground might use their phones to navigate the highways. Farther away, navigation — and the math behind it — becomes a great deal more challenging.

NASA’s Webb to Unveil the Secrets of Nearby Dwarf Galaxies

Mon, 11/25/2019 - 08:39
In two separate studies using NASA’s upcoming James Webb Space Telescope, a team of astronomers will observe dwarf galaxy companions to the Milky Way and the nearby Andromeda galaxy.

NASA Rockets Study Why Tech Goes Haywire Near Poles

Fri, 11/22/2019 - 10:00
A magnetic weak point near the North Pole allows space particles to slip inside our atmosphere, with strange results. Beginning November 25, three NASA-funded rockets will launch through the weak point to find out why.

NASA Space Data Can Cut Disaster Response Times, Costs

Fri, 11/22/2019 - 08:12
According to a new study, emergency responders could cut costs and save time by using near-real-time satellite data along with other decision-making tools after a flooding disaster.

Hubble Eyes an Emitting Galaxy

Fri, 11/22/2019 - 07:30
For this image, the NASA/ESA Hubble Space Telescope turned its powerful eye toward an emission-line galaxy called NGC 3749. It lies over 135 million light-years away and is moderately luminous.

'The Invisible Network' Podcast - Episode 08: Form and Function

Thu, 11/21/2019 - 07:30
"Form follows function" is an oft-cited architectural axiom. In space, form doesn’t necessarily follow function. Human space habitation is rooted, by necessity, in pragmatism. The architectures of Earth won’t work in space, but there is plenty to learn from Earthbound architectural theories as we extend our reach among the stars.

NASA’s Fermi, Swift Missions Enable a New Era in Gamma-ray Science

Wed, 11/20/2019 - 13:00
Two distant explosions first detected by NASA's Fermi Gamma-ray Space Telescope and Neil Gehrels Swift Observatory have produced the highest-energy light yet seen from these events, called gamma-ray bursts (GRBs).

Hubble Studies Gamma-Ray Burst With Highest Energy Ever Seen

Wed, 11/20/2019 - 13:00
NASA’s Hubble Space Telescope has given astronomers a peek at the location of the most energetic outburst ever seen in the universe — a blast of gamma-rays a trillion times more powerful than visible light. That’s because in a few seconds the gamma-ray burst (GRB) emitted more energy than the Sun will provide over its entire 10-billion year life.

Vincent Cecilio – Keeps the Clean Rooms Happy

VIncent Cecilio keeps Goddard's clean rooms happy.

NASA Takes a Cue From Silicon Valley to Hatch Artificial Intelligence Technologies

Tue, 11/19/2019 - 09:00
Could the same computer algorithms that teach autonomous cars to drive safely help identify nearby asteroids or discover life in the universe? NASA scientists are trying to figure that out by partnering with pioneers in artificial intelligence (AI) to apply advanced computer algorithms to problems in space science.

First Detection of Sugars in Meteorites Gives Clues to Origin of Life

Mon, 11/18/2019 - 15:00
An international team has found sugars essential to life in meteorites, supporting the hypothesis that meteorite bombardment on ancient Earth may have assisted the origin of life with a supply of life’s building blocks.

NASA Soil Data Joins the Air Force

Mon, 11/18/2019 - 13:50
SMAP satellite soil moisture measurements now increase the accuracy of Army and Air Force weather forecasts and advisories.

How LISA Pathfinder Detected Dozens of ‘Comet Crumbs’

Mon, 11/18/2019 - 13:00
A team of NASA scientists leveraged LISA Pathfinder's record-setting sensitivity (designed to ripples in space-time produced by, among other things, merging black holes) for a different purpose much closer to home — mapping microscopic dust shed by comets and asteroids.

NASA Scientists Confirm Water Vapor on Europa

Mon, 11/18/2019 - 11:00
Scientists have evidence that one of these ingredients, liquid water, is present under the icy surface of Europa, a moon of Jupiter, and may sometimes erupt into space in huge geysers. Now scientists have detected the water vapor for the first time above Europa’s surface.

A Weakened Black Hole Allows Its Galaxy to Awaken

Mon, 11/18/2019 - 10:01
Astronomers have confirmed the first example of a galaxy cluster where large numbers of stars are being born at its core.

NASA Goddard Honors an Apollo-era Pioneer, His Legacy

Fri, 11/15/2019 - 10:30
Tecwyn Roberts helped set up the Mission Control room in the Apollo era, according to NASA archives.

Hubble Spots a Curious Spiral

Fri, 11/15/2019 - 07:30
Many galaxies we see through telescopes such as the NASA/ESA Hubble Space Telescope, the source of this beautiful image, look relatively similar: spiraling arms, a glowing center, and a mixture of bright specks of star formation and dark ripples of cosmic dust weaving throughout. This galaxy, a spiral galaxy named NGC 772, is no exception.
