NASA's Jet Propulsion Laboratory News and Features 4 Feb 2019, 20:02 UTC For the past several weeks, NASA's InSight lander has been making adjustments to the seismometer it set on the Martian surface on Dec. 19. Now it's reached another milestone by placing a domed shield over the seismometer to help the instrument collect accurate data. The seismometer will give scientists their first look at the deep interior of the Red Planet, helping them understand how it and other rocky planets are formed.
ALMA (Atacama Large Millimetre/Submillimetre Array) 4 Feb 2019, 15:58 UTC Astronomers using ALMA have detected various complex organic molecules around the young star V883 Ori. A sudden outburst from this star is releasing molecules from the icy compounds in the planet forming disk. The chemical composition of the disk is similar to that of comets in the modern Solar System. Sensitive ALMA observations enable astronomers to reconstruct the evolution of organic molecules from the birth of the Solar System to the objects we see today.
NASA's Goddard Space Flight Center 1 Feb 2019, 15:01 UTC This image from the NASA/ESA Hubble Space Telescope reveals an ancient, glimmering ball of stars called NGC 1466. It is a globular cluster — a gathering of stars all held together by gravity — that is slowly moving through space on the outskirts of the Large Magellanic Cloud, one of our closest galactic neighbors.
Universe Awareness - Space Scoop 1 Feb 2019, 10:09 UTC For thousands of years, people have been asking the same questions about the Universe we live in. Does the Universe go on forever or does it have an edge? Has it always existed and if not, how old is it? Around 100 years ago, an astronomer made a major discovery that helped us to answer these questions: he discovered that the Universe is growing.

NASA's Goddard Space Flight Center 30 Jan 2019, 18:00 UTC Scientists have charted the environment surrounding a stellar-mass black hole that is 10 times the mass of the Sun using NASA’s Neutron star Interior Composition Explorer (NICER) payload aboard the International Space Station. NICER detected X-ray light from the recently discovered black hole, called MAXI J1820+070 (J1820 for short), as it consumed material from a companion star. Waves of X-rays formed “light echoes” that reflected off the swirling gas near the black hole and revealed changes in the environment’s size and shape.
MIT 29 Jan 2019, 17:10 UTC After flying in space for more than two years, NASA’s spacecraft OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer) recently entered into orbit around its target, the asteroid Bennu. Asteroids like Bennu are considered to be leftover debris from the formation of our solar system. So, in the first mission of its kind flown by NASA, OSIRIS-REx is looking to retrieve a sample and bring it to Earth.
Cherenkov Telescope Array 29 Jan 2019, 12:09 UTC When we talk about CTA, we usually talk about studying the Universe at the highest energies. Scientists, however, also talk about low energies with CTA, which seems strange because those “low” energies are still a million times higher than the energy of X-rays. Therefore, it’s all a matter of perspective. The low energies from CTA’s perspective are those on the low edge (20 GeV to around 200 GeV) of its full energy range between 20 GeV and 300 TeV. Why are these low energies important and what do scientists hope to discover through their study? This is an overview of why scientists are scrambling to push for excellent sensitivity of CTA in this lower-energy band.
