Scientists use lasers to create the brightest artificial star in the sky

Scientists use lasers to create the brightest artificial star in the sky Late last month, astronomers with the ESO’s Very Large Telescope began operation of a new tool called the Four Laser Guide Star Facility (4LGSF).This incredible new laser rig will create the brightest artificial star ever seen, and use it to produce some of the most incredible imagery we’ve yet to collect about the heavens.

First direct images of a gas giant exoplanet in a triple-star system

First direct images of a gas giant exoplanet in a triple-star system Three hundred and forty light years from Earth, in the constellation Centaurus, there burns a highly unlikely triple star system called HD 131399.It consists of a big, bright star — star A — and a binary pair of stars, B+C.

Astronomers discover Russian nesting supernovas right next door

Astronomers discover Russian nesting supernovas right next door Because it’s so close, M33 is a perennial favorite of amateur astronomers.Using that information, the scientists can tell things like how long the shells have been traveling, and in what direction.

Astronomers discover a ‘starving’ supermassive black hole at the center of a galaxy

Astronomers discover a ‘starving’ supermassive black hole at the center of a galaxy What happens when a black hole falls on hard times?An international team of astronomers have found a black hole that’s rapidly getting dimmer, and they think it’s starving.

Astronomers discover true nature of ‘giant space blob’

Astronomers discover true nature of ‘giant space blob’ We’ve been staring at the first such blob, called Lyman-Alpha blob 1 or LAB-1 for short, since we found it in 2000.The birth of galaxies is not a peaceful process, and these young galaxies could be bombarding the star nurseries with high-energy matter, driving star formation.

Trouble around Mars and Jupiter: this week in space

Trouble around Mars and Jupiter: this week in space NASA and ESA are joining forces to try to re-establish communications between Schiaparelli and its sister spacecraft, TGO, or even Mars Express or the Mars Reconnaissance Orbiter, all of which are active in orbit around Mars.A little further out, Eta Carinae is a colossal binary star system that’s really tearing up its environment.

Scientists will try to directly image Sagittarius A*, the black hole at the center of the Milky Way

Scientists will try to directly image Sagittarius A*, the black hole at the center of the Milky Way To date, we haven’t yet directly imaged a black hole.To solve this problem, eight observatories have joined forces to form the Event Horizon Telescope.

This week in space: a leaked paper on the EM Drive and a supermoon

This week in space: a leaked paper on the EM Drive and a supermoon A recently leaked paper on the controversial and relatively unknown EM Drive led to a lot of articles with titles like “Leaked paper proves EM drive works.” The leaked paper hasn’t made it through peer review, guys, so it has the same scientific reliability as a pile of Bazooka Joe wrapper comics.

This week in space: The future of NASA, the ESA diagnosed its Mars probe failure, and setbacks while resupplying the ISS

This week in space: The future of NASA, the ESA diagnosed its Mars probe failure, and setbacks while resupplying the ISS A Russian Progress spacecraft was lost six minutes into its resupply flight to the ISS on Thursday.But the ISS crew is all fine, they’re not out of supplies, and there’s another resupply flight scheduled for next week.
