New Scientist 8 May 2020, 07:00 UTC When a star passes another star, any planets orbiting them can be flung into space, destroying what could once have been hospitable solar systems. And while rare in the outer parts of our galaxy, such events might be common in the inner regions of the Milky Way.
Universe Today 7 May 2020, 21:48 UTC Astronomy is advancing to the point where we can see planets forming around young stars. This was an unthinkable development only a few years ago. In fact, it was only two years ago that astronomers captured the first image of a newly-forming planet.
Universe Today 7 May 2020, 12:52 UTC If you look out on the sky on a nice clear dark night, you’ll see thousands of intense points of light. Those stars are incredibly far away, but bright enough to be seen with the naked eye from that great distance – a considerable feat. But what you don’t see are all the small stars, the red dwarfs, too small and dim to be seen at those same distances.
Astronomy.com News 7 May 2020, 08:54 UTC Astronomers have discovered a black hole that's closer to Earth than any found before it. Located about 1,000 light-years away in the southern constellation Telescopium, the black hole weighs in at some four times the mass of our Sun, which means it's only about 7.5 miles (12 kilometers) wide.
Centauri Dreams 6 May 2020, 17:06 UTC It will surprise few Centauri Dreams readers that at least some brown dwarfs have bands of clouds, just as we see similar bands on our Solar System’s largest planet. In fact, three brown dwarfs have recently shown signs of cloud banding, and today’s subject, Luhman 16, has previously been analyzed in terms of large cloud patches. I think new work based on data from the European Southern Observatory’s Very Large Telescope (VLT) in Chile may be less significant for what it says about brown dwarfs than what it says about how we study them.
Universe Today 5 May 2020, 20:36 UTC Our Sun is the source of life on Earth. Its calm glow across billions of years has allowed life to evolve and flourish on our world. This does not mean our Sun doesn’t have an active side. We have observed massive solar flares, such as the 1859 Carrington event, which produced northern lights as far south as the Caribbean, and drove electrical currents in telegraph lines. If such a flare occurred in Earth’s direction today, it would devastate our electrical infrastructure. But fortunately for us, the Sun is mostly calm. Unusually calm when compared to other stars.
