What will ancient sedimentary rock tell us about the history of life on Mars?
The new era of space exploration features two Stony Brook University faculty members as part of the development of NASA’s Mars2020 Perseverance rover that recently landed. Distinguished Professor Scott McLennan and Associate Professor Joel Hurowitz both worked on the PIXL (Planetary Instrument for X-ray Lithochemistry) that is attached to the arm of the rover. The PIXL is a micro-focus X-ray fluorescence instrument that rapidly measures elemental chemistry by focusing an X-ray beam to a tiny spot on the target rock or soil, analyzing the induced X-ray fluorescence. Both professors have been working on Mars missions with NASA since 2004.

Hubble Uncovers Concentration of Small Black Holes
Astronomers using the Hubble Space Telescope in their hunt for a massive black hole at the heart of the globular cluster NGC 6397 found something they weren’t expecting: a concentration of smaller black holes lurking there instead. This is a new twist on the search for intermediate-mass black holes. They are the long-sought “missing link” between supermassive black holes and stellar-mass black holes.

Dark Storm on Neptune Reverses Direction, Possibly Shedding a Fragment
A giant dark storm on Neptune heading for certain doom at the equator mysteriously halted its journey and began drifting in the opposite direction. Almost simultaneously, another smaller dark spot appeared nearby, only to vanish months later. Hubble astronomers are presenting these findings today at the Fall 2020 American Geophysical Union meeting.
Powerful electrical events quickly alter surface chemistry on Mars and other planetary bodies
Thinking like Earthlings may have caused scientists to overlook the electrochemical effects of Martian dust storms. On Earth, dust particles are viewed mainly in terms of their physical effects, like erosion. But, in exotic locales from Mars to Venus to Jupiter’s icy moon Europa, electrical effects can affect the chemical composition of a planetary body’s surface and atmosphere in a relatively short time, according to research from Washington University in St. Louis.
Hubble Pins Down Weird Exoplanet with Far-Flung Orbit
Astronomers analyzing Hubble images of the double star, HD 106906, have discovered a planet in a huge 15,000-year-long orbit that sweeps it as far from its stellar duo as Planet Nine would be from our Sun. This is observational evidence that similarly far-flung worlds may exist around other stars. Researchers hypothesize that the planet wound up there in a game of planetary pinball where the gravitational pull of a passing star modified the orbit’s shape.

Best Region For Life on Mars Was Far Below Surface
The most habitable region for life on Mars would have been up to several miles below its surface, likely due to subsurface melting of thick ice sheets fueled by geothermal heat, a Rutgers-led study concludes. The study, published in the journal Science Advances, may help resolve what’s known as the faint young sun paradox – a lingering key question in Mars science.
Scientists Solve Big Limitation of Stratospheric Balloon Payloads
Nearly all photons emitted after the Big Bang are now visible only at far-infrared wavelengths. Earth’s atmosphere blocks most of this light, so scientists are turning to huge stratospheric balloons to explore it. However, it is quite difficult to cool a telescope the size of a living room to nearly absolute zero while flying it from a balloon. This is where the Balloon-Borne Cryogenic Telescope Testbed comes in. NASA researchers discuss the mission in Review of Scientific Instruments.

Hubble Launches Large Ultraviolet-Light Survey of Nearby Stars
This is a ground-based telescopic photo of the Large Magellanic Cloud, a satellite galaxy of our Milky Way. The LMC is one of several select targets of a new initiative with NASA’s Hubble Space Telescope, called ULLYSES (UV Legacy Library of Young Stars as Essential Standards). The program is looking at over 300 stars to build an ultraviolet-light catalog for capturing the diversity of stars, from young to old, to give astronomers a much better understanding of the birth of stars and how this relates to everything from planets to the formation and evolution of galaxies.
