7 Mar 2018, 11:00 UTC New data from the Atacama Large Millimeter/submillimeter Array (ALMA) and other telescopes have been used to create this stunning image showing a web of filaments in the Orion Nebula. These features appear red-hot and fiery in this dramatic picture, but in reality are so cold that astronomers must use telescopes like ALMA to observe them. Next Previous

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.

15 Feb 2018, 16:10 UTC The biggest black holes in the Universe are growing faster than the rate of stars being formed in their galaxies, according to two new studies using data from NASA's Chandra X-ray Observatory and other telescopes. Next Previous
14 Feb 2018, 15:00 UTC Beauty, grace, mystery — this magnificent spiral galaxy has all the qualities of a perfect galactic Valentine. Captured by the NASA/ESA Hubble Space Telescope, the galaxy NGC 3344 presents itself face-on, allowing astronomers a detailed look at its intricate and elegant structure. And Hubble’s ability to observe objects over a wide range of different wavelengths reveals features that would otherwise remain invisible. Next Previous
5 Feb 2018, 16:00 UTC A new study has found that the seven planets orbiting the nearby ultra-cool dwarf star TRAPPIST-1 are all made mostly of rock, and some could potentially hold more water than Earth. The planets' densities, now known much more precisely than before, suggest that some of them could have up to 5 percent of their mass in the form of water — about 250 times more than Earth's oceans.

31 Jan 2018, 23:41 UTC A new self-portrait of NASA's Curiosity Mars rover shows the vehicle on Vera Rubin Ridge, which it has been investigating for the past several months. Directly behind the rover is the start of a clay-rich slope scientists are eager to begin exploring. In coming weeks, Curiosity will begin to climb this slope. In the image, north is on the left and west is on the right, with Gale Crater's rim on the horizon of both edges. Next Previous
ASI Agenzia Spaziale Italiana 15 Mar 2018, 16:53 UTC VegaC will be launched with the new P120 engine, common to all the ESA launcher family, which is in an advanced phase of development. The new second stage Zefiro40 engine has been successfully tested last week in Sardinia.
NASA's Goddard Space Flight Center 15 Mar 2018, 14:39 UTC NASA has powered on its latest space payload to continue long-term measurements of the Sun's incoming energy. Total and Spectral solar Irradiance Sensor (TSIS-1), installed on the International Space Station, became fully operational with all instruments collecting science data as of this March.
NASA's Goddard Space Flight Center 15 Mar 2018, 14:29 UTC Glowing in mostly purple and green colors, a new celestial phenomenon is sparking the interest of scientists, photographers and astronauts. The display was initially discovered by a group of citizen scientists who took pictures of the unusual lights and playfully named them "Steve." Scientists have since learned more about the purples and greens, and have given it a more accurate name: Strong Thermal Emission Velocity Enhancement, which can still can be shortened to STEVE.
University of New Hampshire 15 Mar 2018, 13:30 UTC It might sound like something from a science fiction plot — astronauts traveling into deep space being bombarded by cosmic rays — but radiation exposure is science fact. As future missions look to travel back to the moon or even to Mars, new research from UNH’s Space Science Center cautions that the exposure to radiation is much higher than previously thought and could have serious implications for both astronauts and satellite technology.

Astro Bob 18 Mar 2018, 16:55 UTC We had a fine but brief display of the aurora this week over the northern states and Canada on Thursday night, March 15. Would that we all could have seen it from Sweden’s Lapland. That’s the location of the video, and it was made on March 14 local time. Some of us have seen auroral displays like this one, but few videos I’ve seen capture it live (no time lapse) so well. I don’t even mind the the twisting and turning of the camera. During a major aurora, things happen so fast, your neck swivels about like Elvis’s hips — you don’t want to miss a thing!
All About Space 18 Mar 2018, 07:00 UTC The simple answer is gravity. Imagine each of the particles that make up Saturn’s rings as moons in orbit around the gaseous body of the planet. Each of these particles is in freefall – like the ISS is as it orbits around Earth.

New Scientist 16 Mar 2018, 16:30 UTC Jocelyn Bell Burnell, the astrophysicist who discovered pulsars as a postgraduate student, is now in her 70s. She tends her garden. She collects poetry with an astronomical theme. She also campaigns tirelessly for the involvement and recognition of women in science, and loves to share her intellectual passions by any means at hand. At 11.30 am on Sunday, she joins an orchestra in London to explore our relationship with the cosmos.
SpaceFlight Insider 16 Mar 2018, 16:15 UTC Following a public naming campaign that drew 115,000 participants, NASA’s New Horizons team has selected the name Ultima Thule for the spacecraft’s second target, Kuiper Belt Object (KBO) 2014 MU69, which the probe is scheduled to fly past on New Year’s Day 2019.
