Square Kilometer Array 1 Mar 2018, 08:05 UTC In a paper published in the journal Nature yesterday, a team of US astronomers announced the detection of a signal from the first stars to have emerged in the Universe, about 180 million years after the Big Bang. After the Big Bang, the universe cooled and went dark for millions of years. In the darkness, gravity pulled matter together until stars formed and burst into life, bringing the ‘Cosmic Dawn’.
NASA's Jet Propulsion Laboratory News and Features 28 Feb 2018, 20:02 UTC NASA's Mars Curiosity rover has conducted the first test of a new drilling technique on the Red Planet since its drill stopped working reliably.
MIT 28 Feb 2018, 17:59 UTC In a study published today in the journal Nature, astronomers from MIT and Arizona State University report that a table-sized radio antenna in a remote region of western Australia has picked up faint signals of hydrogen gas from the primordial universe.
SETI Institute 27 Feb 2018, 18:46 UTC New Studies of Clay Formation Provide Clues about Early Martian Climate: A new climate model was developed for Mars that better explains how clays formed on the surface. Short-term warm and wet environments, occurring sporadically in a generally cold early Mars, are proposed to explain formation of surface clays on Mars.
ESA Science & Technology 27 Feb 2018, 09:22 UTC Last year, ESA's Gaia mission helped astronomers make unique observations of Neptune's largest moon, Triton, as it passed in front of a distant star. This is a preview of the superb quality and versatility of the Gaia data that will be released in April.
Harvard-Smithsonian Center for Astrophysics 26 Feb 2018, 19:09 UTC A team of astrophysicists and planetary scientists has predicted that Neptune-like planets located near the center of the Milky Way galaxy have been transformed into rocky planets by outbursts generated by the nearby supermassive black hole. These findings combine computer simulations with data from recent exoplanet findings, and X-ray and ultraviolet observations of stars and black holes.
National Radio Astronomy Observatory (NRAO) 26 Feb 2018, 13:50 UTC Space weather emitted by Proxima Centauri, the star closest to our sun, may make that system rather inhospitable to life after all. Using data from the Atacama Large Millimeter/submillimeter Array (ALMA), a team of astronomers discovered that a powerful stellar flare erupted from Proxima Centauri last March. This finding, published in the Astrophysical Journal Letters, raises questions about the habitability of our solar system’s nearest exoplanetary neighbor, Proxima b, which orbits Proxima Centauri.
Planetary Science Institute 26 Feb 2018, 07:00 UTC Spacecraft landing on Jupiter’s moon Europa could see the craft sink due to high surface porosity, research by Planetary Science Institute Senior Scientist Robert Nelson shows. Nelson was the lead author of a laboratory study of the photopolarimetric properties of bright particles that explain unusual negative polarization behavior at low phase angles observed for decades in association with atmosphereless bodies including asteroids 44 Nysa, 64 Angelina and the Galilean satellites Io, Europa and Ganymede.
