Researchers have seen newborn red stars dimly shining from the cocoons of dust and gas out of which they formed.
Astronomers made this discovery using the European Southern Observatory’s Visible and Infrared Survey Telescope for Astronomy (VISTA), which studies the near-infrared part of the spectrum.
Fortunately, dust does not block near-infrared radiation as it does visible light, so the telescope can image small, cool stars. VISTA, which uses a mirror 4.1 meters in diameter, is part of
Saturn’s moon Dione has joined the growing list of watery bodies in our solar system.
Data from NASA’s Cassini probe indicate that a liquid ocean some 20 miles deep exists far below the icy surface of the moon. This means that its interior looks similar to two other Saturnian moons, Titan and Enceladus, both of which hide vast oceans beneath a thin crust of ice. Dione is likely different in at least one respect though: the data indicate it’s ocean buried much deeper.
Like many other space enthusiasts around the world, I woke up today in a bittersweet mood as I read the reports about the death of the European Space Agency’s Rosetta comet probe. Its demise was carefully planned and long foretold but was sad all the same, putting a period at the end of a story that rolling out for more than 12 years. During that time, Rosetta made three passes by Earth, one by Mars, visited a pair of asteroids, and spent more than two years scrutinizing Comet 67P/Churyumo
Talk of sending humans to Mars hit a fever pitch this week following SpaceX founder Elon Musk’s big announcement Tuesday.
He outlined an ambitious plan to begin sending cargo missions to Mars by 2018, with the first manned missions leaving by 2022 or 2023. Along the way, he hopes to improve the cost of trips by “5 million percent”, and establish a colony of 1 million souls there within 40 to 100 years. Let’s just say people had questions — The Verge’s Loren G
