Astronomers using W. M. Keck Observatory on Maunakea, Hawaii Island have discovered one of the lowest-mass planets whose images have been directly captured. Not only were they able to measure its mass, but they were also able to determine that its orbit is similar to the giant planets in our own solar system.
The planet, called AF Lep b, is among the first ever discovered using a technique Never before seen way to annihilate a star

Astronomers studying a powerful gamma-ray burst (GRB) with the Gemini South telescope, operated by NSF's NOIRLab, may have detected a never-before-seen way to destroy a star. Unlike most GRBs, which are caused by exploding massive stars or the chance mergers of neutron stars, astronomers have concluded that this GRB came instead from the collision of stars or stellar remnants in the jam-packed e Molecular filament shielded young solar system from supernova

Isotope ratios found in meteorites suggest that a supernova exploded nearby while the Sun and Solar System were still forming. But the blast wave from a supernova that close could have potentially destroyed the nascent Solar System. New calculations shows that a filament of molecular gas, which is the birth cocoon of the Solar System, aided the capture of the isotopes found in the meteorites, wh Ovzon 3 on course to miss regulatory deadline after latest delay

Video: BepiColombo's third Mercury flyby

Watch Mercury appear from the shadows as the ESA/JAXA BepiColombo spacecraft sped by the planet's night side during its 19 June 2023 close flyby, and enjoy a special flyover of geologically rich terrain.
In the first part of the movie, composed of 217 images captured by BepiColombo's monitoring camera M-CAM 3, the planet's illuminated side quickly appears in the spacecraft's field of view, showing off a bounty of geological features on its surface. The planet's terminator—the divide between day and night—becomes more distinctive from afar, adding to the beauty of the image sequence. At one point Mercury momentarily appears to hang between the spacecraft's body and antenna before the spacecraft speeds away.
The image sequence starts from 19:46:25 UTC on 19 June 2023, at an altitude of 1,789 km above the planet's surface, and ends at 20:34:25 UTC on 20 June 2023, when BepiColombo was 331,755 km away.
