Nanowerk Space Exploration News 10 Dec 2019, 09:26 UTC Scientists from Moscow Institute for Physics and Technology, Space Research Institute of the Russian Academy of Sciences (IKI), and Pulkovo Observatory discovered a unique neutron star, the magnetic field of which is apparent only when the star is seen under a certain angle relative to the observer.
Starts With a Bang! 9 Dec 2019, 15:01 UTC Hubble has been operational for nearly 30 years, and still produces the most spectacular images of all. Here are this year’s best.
SciTech Daily 9 Dec 2019, 13:46 UTC An international group of scientists, including Andrey Savelyev, associate professor of the Institute of Physical and Mathematical Sciences and Information Technologies of the IKBFU, has improved a computer program that helps simulate the photons.
Scientific American 9 Dec 2019, 12:47 UTC The hunt for dark matter—and the associated particles and forces that we expect to accompany it—has turned up numerous false dawns over the years. Try as we might, any evidence of what makes up this invisible form of matter—thought to be the vast majority of matter in the known universe—has remained elusive. But a team of Hungarian researchers suggested in 2015 that they had found a particle, dubbed X17, that possibly interacted with dark matter in some way. Recently, in a second experiment, the team says it has fresh evidence for the X17 particle, which would change physics as we know it. But not everyone is convinced, and new experimental plans are afoot to root out the truth.
Scientific American 9 Dec 2019, 12:45 UTC Humans have been mapping other worlds since we peered at the Moon with our eyes and gazed at Mars through our earliest telescopes. But it can be a painstaking process. That's especially true for places that are very distant and very shrouded by their atmospheres.
New Scientist 6 Dec 2019, 19:05 UTC It’s comet 2I/Borisov’s time to shine. The interstellar comet has been steadily getting brighter since it was first spotted in September, and now it’s reaching its brightest moments as it passes close to the sun and Earth.
Centauri Dreams 6 Dec 2019, 17:52 UTC Calling it a ‘chance discovery,’ the University of Warwick’s Boris Gänsicke recently presented the results of his team’s study of some 7,000 white dwarf stars, all of them cataloged by the Sloan Digital Sky Survey. One drew particular interest because chemical elements turned up in spectroscopic studies indicating something unusual. Says Gänsicke, “We knew that there had to be something exceptional going on in this system, and speculated that it may be related to some type of planetary remnant.”
ESO Blog 6 Dec 2019, 11:00 UTC Measuring a whopping twelve metres across, APEX is a submillimetre-wavelength telescope operating in the southern hemisphere and has a suite of instruments to find out more about the “cold”, “dusty” and “distant” Universe. APEX is operated by ESO on behalf of the Max Planck Institute for Radio Astronomy, the Onsala Space Observatory and ESO itself, meaning that many ESO astronomers get to spend time at the telescope each year. ESO Student Katja Fahrion tells us about her recent experience observing with this special machine.
New Scientist 6 Dec 2019, 08:00 UTC Dead stars are exploding all around the universe and we aren’t really sure why – but now a pair of researchers think that minuscule black holes made from dark matter might be to blame. Burnt out stars known as white dwarfs can ignite into a type Ia supernova when they gather matter from a neighbouring star or merge with other astronomical objects. Exactly how this works is still an open question.
