Scientists have painted the most detailed portrait yet of the planetary system orbiting Barnard’s Star. Unfortunately, the picture is not encouraging, as all four planets appear to be "extremely uninhabitable." from Universe Today https://ift.tt/B735bR1 via IFTTT

Astronomers have found four new white dwarfs within about 65 light years. Even though the sky has been studied thoroughly, these escaped detection. That's because they're tight binaries with red dwarf partners, and the much brighter red dwarfs hide the white dwarfs. The binaries used to share common envelopes. from Universe Today https://ift.tt/0PJIKhq via IFTTT

A Sun-like star orbits the supermassive black hole in our Milky Way so closely that it comes within the distance of Neptune's orbit of the Sun. It has a top speed of more than 8% of light speed. With such extreme motion the star gives astronomers the opportunity to test the limits of general relativity. from Universe Today https://ift.tt/7N8EZeP via IFTTT

Astronomers have solved a decades old puzzle about the Sun's missing silver, not by finding something new, but by modelling something old far more accurately. A revised, more realistic model of the Sun's atmosphere reveals it actually contains 55 per cent more silver than previously calculated, finally matching what meteorites have been telling us all along. It's a quiet reminder that some of the biggest revelations in astronomy come not from new data, but from asking familiar questions with sharper tools. from Universe Today https://ift.tt/PfgY7wc via IFTTT

Astronomers have detected an atmosphere around a rocky planet in another star's habitable zone for the very first time. It’s a milestone that brings us a step closer to answering whether life could exist beyond our Solar System. Predicted by a mathematical model before it was ever observed, and confirmed using a rare planetary alignment 48 light years away, this discovery does more than identify one intriguing world, it provides us with a whole new way to search for others like it. from Universe Today https://ift.tt/PSgyxID via IFTTT

Somewhere in the Milky Way Galaxy is an old star that has lost one of its comets. By some quirk of orbital mechanics, that frozen nucleus of ice and dust got kicked out of its home system and into a long and winding trajectory across space.

There are parts of the universe that are extremely hard to see, even for our most advanced telescopes. Gas and dust don’t emit any light, and are only visible by the light that they happen to block from stars and galaxies. Magnetic fields are even harder since regular light typically passes right through them. However, according to a new paper available in pre-print on arXiv, by Manisha Caleb of the University of Sydney and their co-authors, we’re currently commissioning a potentially game-changing new tool that could use a particularly violent astronomical phenomenon to provide new insight into these hard to see places. from Universe Today https://ift.tt/rjQ3Ox6 via IFTTT

Astrobiology has long been split into two camps: a search for "biosignatures" and a search for "intelligence." These look for very different things, but they also leave a huge gap in between. It took 3.5 billion years for us to go from the first microbe to a civilization that sent radio waves out into the cosmos. Detecting life in between those stages is a relatively untouched aspect of astrobiology—which is also the focal point of a new paper, "Signs and Signatures of Intelligence", available in pre-print on arXiv, by astrobiologist Julia DeMarines. from Universe Today https://ift.tt/pFP0X6R via IFTTT

When a massive star reaches the end of its life, it explodes as a supernova that can light up the sky for months.
