NASA’s Planet Hunter Completes Its Primary Mission

Tue, 08/11/2020 - 11:00
NASA's TESS has completed its primary mission, imaging about 75% of the starry sky during a two-year-long survey. TESS has found 66 new planets, nearly 2,100 candidates, and much more.

Laser Beams Reflected Between Earth and Moon Boost Science

Mon, 08/10/2020 - 10:00
After launching laser beams for years to NASA's Moon orbiter, scientists receive signal back for the first time.

NASA Sounding Rocket Finds Helium Structures in Sun’s Atmosphere

Fri, 08/07/2020 - 12:00
Helium is the second most abundant element in the universe after hydrogen. But scientists aren’t sure just how much there actually is in the Sun’s atmosphere. NASA's HERSCHEL sounding rocket has taken the first global measurements of helium in the extended solar atmosphere – a key piece of information for understanding our space environment.

Hubble Sees Near and Far

Fri, 08/07/2020 - 07:45
The barred spiral galaxy known as NGC 4907 shows its starry face from 270 million light-years away to anyone who can see it from the Northern Hemisphere. Appearing in this Hubble image to shine brightly below the galaxy is a star that is actually within our own Milky Way galaxy.

NASA’s OSIRIS-REx is One Rehearsal Away from Touching Asteroid Bennu

Thu, 08/06/2020 - 14:00
NASA’s first asteroid sampling spacecraft is making final preparations to grab a sample from asteroid Bennu’s surface.

NASA’s MAVEN Observes Martian Night Sky Pulsing in Ultraviolet Light

Thu, 08/06/2020 - 11:30
Vast areas of the Martian night sky pulse in ultraviolet light, according to images from NASA’s MAVEN spacecraft. The results are being used to illuminate complex circulation patterns in the Martian atmosphere.

Hubble Uses Earth as a Proxy for Identifying Oxygen on Potentially Habitable Planets Around Other Stars

Thu, 08/06/2020 - 10:00
Taking advantage of a total lunar eclipse, Hubble used the Moon as a mirror to study sunlight that had passed through Earth's atmosphere. As a result, Hubble detected Earth's own brand of sunscreen – ozone – in our atmosphere. The technique simulates how scientists will search for evidence of life on planets around other stars.

Uncovering Our Solar System’s Shape

Wed, 08/05/2020 - 10:00
Scientists have developed a new prediction of the shape of the bubble surrounding our solar system using a model developed with data from NASA missions.

NASA Scientists Leverage Carbon-Measuring Instrument for Mars Studies

Wed, 08/05/2020 - 08:04
Insights and technology gleaned from creating a carbon-measuring instrument for Earth climate studies is being leveraged to build another that would remotely profile, for the first time, water vapor up to nine miles above the Martian surface, along with wind speeds and minute particles suspended in the atmosphere.

Rocket Sees Curling Waves Above Alaskan Sky

Tue, 08/04/2020 - 11:00
The curling waves of the Kelvin-Helmholtz instability – appearing briefly in the center of the image before dissipating – may explain how gases mix in otherwise stable layers of the atmosphere.

NASA Sun Data Helps New Model Predict Big Solar Flares

Fri, 07/31/2020 - 11:36
Using data from NASA’s Solar Dynamics Observatory, or SDO, scientists have developed a new model that successfully predicted seven of the Sun’s biggest flares from the last solar cycle, out of a set of nine. With more development, the model could be used to one day inform forecasts of these intense bursts of solar radiation.
