Universities Space Research Association 3 Jan 2020, 19:15 UTC New research led by Universities Space Research Association (USRA) and published today in Science Advances shows that lava flows on Venus may be only a few years old, suggesting that Venus could be volcanically active today — making it the only planet in our solar system, other than Earth, with recent eruptions.
NASA's Goddard Space Flight Center 3 Jan 2020, 12:30 UTC This smattering of celestial sequins is a spiral galaxy named NGC 4455, located in the northern constellation of Coma Berenices (Berenice’s Hair). This might sound like an odd name for a constellation — and in fact it is somewhat unusual. It’s the only modern constellation to be named in honor of a real person from history: Queen Berenice II of Egypt.
Hubble Space Telescope News 2 Jan 2020, 09:00 UTC In April 2020, the NASA/ESA Hubble Space Telescope will celebrate 30 years since its launch. ESA/Hubble has produced a commemorative calendar of the telescope’s Hidden Gems that is now available for everyone to use and enjoy.
MIT 1 Jan 2020, 18:59 UTC A conventional compass would be of little use on the moon, which today lacks a global magnetic field. But the moon did produce a magnetic field billions of years ago, and it was likely even stronger than the Earth’s field today. Scientists believe that this lunar field, like Earth’s, was generated by a powerful dynamo — the churning of the moon’s core. At some point, this dynamo, and the magnetic field it generated, petered out.
NASA Breaking News 31 Dec 2019, 14:27 UTC NASA researchers will present new findings on a wide range of astrophysics and other space science topics at the 235th Meeting of the American Astronomical Society, Saturday, Jan. 4, through Wednesday, Jan. 8, in Honolulu. NASA-related briefings will stream live on the agency’s website.
ESA Top News 30 Dec 2019, 09:43 UTC As the year comes to a close, it is once again time to look back and reflect on some of the achievements and highlights of European spaceflight. The new Gaia star catalogue and the launch of Cheops are keeping ESA at the forefront of space science, as will Solar Orbiter, being prepared for launch next year.
Harvard-Smithsonian Center for Astrophysics 28 Dec 2019, 13:45 UTC As the holiday season approaches, people in the northern hemisphere will gather indoors to stay warm. In keeping with the season, astronomers have studied two groups of galaxies that are rushing together and producing their own warmth. The majority of galaxies do not exist in isolation. Rather, they are bound to other galaxies through gravity either in relatively small numbers known as "galaxy groups," or much larger concentrations called "galaxy clusters" consisting of hundreds or thousands of galaxies. Sometimes, these collections of galaxies are drawn toward one another by gravity and eventually merge.
ESA Top News 23 Dec 2019, 21:43 UTC Solar Orbiter, an ESA-led mission with strong NASA participation, will provide the first views of the Sun's unchartered polar regions from high-latitudes, giving unprecedented insight into how our parent star works. This important mission will also investigate the Sun-Earth connection, helping us to better understand and predict periods of stormy space weather.
NASA's Goddard Space Flight Center 20 Dec 2019, 12:30 UTC This image from the NASA/ESA Hubble Space Telescope shows IC 2051, a galaxy in the southern constellation of Mensa (the Table Mountain) lying about 85 million light-years away. It is a spiral galaxy, as evidenced by its characteristic whirling, pinwheeling arms, and it has a bar of stars slicing through its center.
