Astronomers Spot Potential First Evidence of New Planet Being Born
Astronomers believe they may have found the first direct evidence of a new planet being born. A dense disc of dust and gas has been spotted surrounding a young star called AB Aurigae, about 520 light years away from Earth. From a report: Using the European Southern Observatory’s Very Large Telescope (VLT), located in Chile, the researchers observed a spiral structure…
Very Large Telescope sees signs of planet birth
Observations made with the European Southern Observatory’s Very Large Telescope (ESO’s VLT) have revealed the telltale signs of a star system being born. Around the young star AB Aurigae lies a dense disc of dust and gas in which astronomers have spotted a prominent spiral structure with a ‘twist’ that marks the site where a planet may be forming. The observed…
Scientists puzzle over massive, never-before-seen star system in the Milky Way
Earlier this year, an international team of scientists announced the second detection of a gravitational-wave signal from the collision of two neutron stars. The event, called GW190425, is puzzling: The combined mass of the two neutron stars is greater than any other observed binary neutron star system. The combined mass is 3.4 times the mass of our sun.

Closest Black Hole To Earth Found ‘Hiding in Plain Sight’
The massive cosmic object lurks in a star system you can see with the naked eye. From a report: During winter in the Southern Hemisphere, a blue point of light in the constellation Telescopium gleams overhead. The brilliant pinprick on the sky, which looks like a bright star, is actually two stars in close orbit — accompanied by the closest known…

Meet Regulus, the Lion’s Heart
The bright star Regulus is very prominent in the evening sky in May. It looks like a single point of light, but is really 4 stars. It’s the brightest star in the constellation Leo the Lion. Source: https://earthsky.org/brightest-stars/best-regulus-the-heart-of-the-lion…
Are these 19 eccentric asteroids from other star systems?
In the first discovery of its kind, researchers in France have found 19 asteroids in our solar system – between the planets Jupiter and Neptune – that they say are likely of interstellar origin. Source: https://earthsky.org/space/19-interstellar-asteroids-in-our-solar-system-centaurs…
