Astronomy and Space news
 | Data reveals evidence of molecular absorption in the atmosphere of a hot NeptuneAn international team of scientists recently measured the spectrum of the atmosphere of a rare hot Neptune exoplanet, whose discovery by NASA's Transiting Exoplanet Survey Satellite (TESS) was announced just last month. |
 | Tiny moon shadows may harbor hidden stores of iceHidden pockets of water could be much more common on the surface of the moon than scientists once suspected, according to new research led by the University of Colorado Boulder. In some cases, these tiny patches of ice might exist in permanent shadows no bigger than a penny. |
 | New sub-Saturn-mass exoplanet discoveredUsing the microlensing technique, an international team of astronomers has detected a new distant alien world. The newly found exoplanet, designated OGLE-2018-BLG-0799Lb, is about five times less massive than Jupiter and orbits a very low-mass dwarf. The finding is reported in a paper published October 17 on the arXiv pre-print server. |
 | SOFIA discovers water on sunlit surface of moonNASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) has confirmed, for the first time, water on the sunlit surface of the Moon. This discovery indicates that water may be distributed across the lunar surface, and not limited to cold, shadowed places. |
 | Asteroid samples escaping from jammed NASA spacecraftA NASA spacecraft is stuffed with so much asteroid rubble from this week's grab that it's jammed open and precious particles are drifting away in space, scientists said Friday. |
 | OSIRIS-REx spacecraft collects large sample of asteroid surface material, NASA confirmsTwo days after touching down on asteroid Bennu, NASA's University of Arizona-led OSIRIS-REx mission team received images confirming that the spacecraft has collected more than enough material to meet one of its main mission requirements—acquiring at least 2 ounces, or 60 grams, of the asteroid's surface material. |
 | The first habitable-zone, Earth-sized planet discovered with exoplanet survey spacecraftTESS, the Transiting Exoplanet Survey Satellite, was launched in 2018 with the goal of discovering small planets around the Sun's nearest neighbors, stars bright enough to allow for follow-up characterizations of their planets' masses and atmospheres. TESS has so far discovered seventeen small planets around eleven nearby stars that are M dwarfs—stars that are smaller than the Sun (less than about 60% of the Sun's mass) and cooler (surface temperatures less than about 3900 kelvin). In a series of three papers that appeared together this month, astronomers report that one of these planets, TOI-700d, is Earth-sized and also located in its star's habitable zone; they also discuss its possible climate. |
 | Astronomers enlist AI in the search for 'lethal' baby star eruptionsYoung stars—just like young humans—are prone to temper flares. But star flares can incinerate everything around them, including the atmospheres of nearby planets starting to form. |
 | Study offers more complete view of massive asteroid PsycheA new study authored by Southwest Research Institute planetary scientist Dr. Tracy Becker discusses several new views of the asteroid 16 Psyche, including the first ultraviolet observations. The study, which was published today in The Planetary Science Journal and presented at the virtual meeting of the American Astronomical Society's Division for Planetary Sciences, paints a clearer view of the asteroid than was previously available. |
 | The magnetic fields of the jellyfish galaxy JO206An international team of astronomers has gained new insights into the physical conditions prevailing in the gas tail of so-called jellyfish galaxies. They are particularly interested in the parameters that lead to the formation of new stars in the tail outside the galaxy disk. They analyzed, for example, the strength and orientation of the magnetic fields in the galaxy JO206. |
 | OSIRIS-REx spacecraft goes for early stow of asteroid sampleNASA's OSIRIS-REx mission is ready to perform an early stow on Tuesday, Oct. 27, of the large sample it collected last week from the surface of the asteroid Bennu to protect and return as much of the sample as possible. |
 | About 3% of Starlink satellites have failed so farSpaceX has drawn plenty of praise and criticism with the creation of Starlink, a constellation that will one day provide broadband internet access to the entire world. To date, the company has launched over 800 satellites and (as of this summer) is producing them at a rate of about 120 a month. There are even plans to have a constellation of 42,000 satellites in orbit before the decade is out. |
 | SpaceX starship passes static fire test with three raptor engines, finally gets nose coneIt's beginning to look like SpaceX will attempt to make the 15-kilometer (9.3-mile) hop test before Christmas. After two successful 150-meter (~500 foot) hops with the SN5 and SN6 prototypes, engineers at SpaceX's Boca Chica launch facility in South Texas rolled out the SN8—the first Starship prototype to have three Raptor engines. But before the SN8 can conduct a high-altitude test flight, the engineers needed to run a static fire test. |
Technology news
