New Image Reveals Secrets of Planet Birth

The background of this image is dark, but in its centre lurks a swirling ghostly figure, which extends towards the edge of the picture. At the very centre there is a small bright region and erupting out of it there is a poorly defined, fuzzy edged cloud and blobs of material in yellow and blue, respectively. The yellow cloud extends far out in the image, making an elongated spiral shape that gets dimmer and less defined as it reaches the top and bottom of the frame. Meanwhile, the blue blobs only extend downwards from the centre and to a fraction of the distance of the yellow spiral cloud. The blobs twist away from the central bright region, forming a tight U-shape lying on its right side.
A spectacular new image released today by the European Southern Observatory gives us clues about how planets as massive as Jupiter could form. Using ESO’s Very Large Telescope (VLT) and the Atacama Large Millimeter/submillimeter Array (ALMA), researchers have detected large dusty clumps, close to a young star, that could collapse to create giant planets.

Astronomers reveal First Image of the Black Hole at the Heart of our Galaxy

EHT image of Sgr A* (top; Paper I). Ring-like images dominate the wide range of images obtained across multiple methods, however, variability and sparse visibility domain coverage make selection of a single image impossible (Paper III). The inset images represent different imaging solutions and their associated frequency (histograms).

Astronomers have unveiled the first image of the supermassive black hole at the centre of our own Milky Way galaxy. This result provides overwhelming evidence that the object is indeed a black hole and yields valuable clues about the workings of such giants, which are thought to reside at the centre of most galaxies...

Findings could help shed light on how galaxies and their supermassive black holes form. It’s about 660 million times as massive as our sun, and a cloud of gas circles it at about 1.1 million mph. This supermassive black hole sits at the center of a galaxy NGC 1332, 73 million light years from Earth. And an international team of scientists that includes Rutgers associate professor Andrew J. Baker has measured its mass with unprecedented accuracy with Atacama Large Millimeter/submillimeter Array (ALMA).

A black hole can form after matter, often from an exploding star, condenses via gravity...
