A newly discovered asteroid will swing past Earth this weekend, coming closer than the Moon

In this artist's conception, a black hole (center) is contained in a small host galaxy in the distant universe (left). In the nearby universe (right), the same sized black hole would be hosted in a much bigger galaxy. Credit: CfA/Melissa Weiss

JWST turns up even more heavier-than-expected black holes

A Hubble Space Telescope image of the host galaxy of an exceptionally powerful fast radio burst, FRB 20220610A. Hubble’s sensitivity and sharpness reveals a compact group of multiple galaxies that may be in the process of merging. They existed when the universe was only 5 billion years old.

Much of the mass in the El Gordo galaxy cluster is actually dark matter, shown here artificially colorized in blue. Scientists determined the location and concentration of the cluster’s dark matter by observing how its mass distorted the light from distant galaxies behind the cluster. Credit: NASA, ESA, and J. Jee (University of California, Davis).

Ask Astro: If dark matter is invisible, then how do we detect it?

This 2008 image from the Hubble Space Telescope indicates that a huge ring of dark matter likely exists surrounding the center of CL0024+17 that has no normal matter counterpart. Credit: NASA.

Dark matter might keep itself company, and that helps solve 2 cosmic puzzles

The Milky Way (green) lies in an area with little matter. The galaxies in the bubble move in the direction of the higher matter densities (red arrows). The universe therefore appears to be expanding faster inside the bubble. Credit: AG Kroupa/University of Bonn

JWST finds oldest black hole ever seen, and it’s hungry

Clementine observes the Moon, solar corona, and Venus in 1994. In this picture the Moon is seen illuminated solely by light reflected from the Earth — Earthshine! The bright glow on the lunar horizon is caused by light from the solar corona; the sun is just behind the lunar limb. Caught in this image is the planet Venus at the top of the frame. Credit: NASA
