Is an 'off-year' Leonid outburst in the cards for November?

It's still one of the coolest things I ever saw. I was in the U.S. Air Force in the 90s, and November 1998 saw me deployed to the dark skies of Kuwait. That trip provided an unexpected treat, as the Leonid meteors hit dramatic ...

New research challenges dark matter theory in galaxy formation

The standard model for how galaxies formed in the early universe predicted that the James Webb Space Telescope (JWST) would see dim signals from small, primitive galaxies. But data are not confirming the popular hypothesis ...

Monitoring Webb's mirrors for optimal optics

NASA's James Webb Space Telescope is the largest and most powerful telescope ever launched to space. Its mirror is composed of 18 individual segments that have been aligned so accurately, that they effectively work as a single ...

Hubble captures barred spiral galaxy NGC 1672

This NASA/ESA Hubble Space Telescope image features NGC 1672, a barred spiral galaxy located 49 million light-years from Earth in the constellation Dorado. This galaxy is a multi-talented light show, showing off an impressive ...

A space walking robot could build a giant telescope in space

The Hubble Space Telescope was carried to space inside the space shuttle Discovery and then released into low-Earth orbit. The James Webb Space Telescope was squeezed inside the nose cone of an Ariane 5 rocket and then launched. ...

Astrophysicists use echoes of light to illuminate black holes

A team of astrophysicists, led by scholars from the Institute for Advanced Study, has developed an innovative technique to search for black hole light echoes. Their novel method, which will make it easier for the mass and ...

Astronomers discover a new repeating fast radio burst

Using the CHIME telescope, an international team of astronomers has detected a new repeating fast radio burst (FRBs) source in the outskirts of a quiescent galaxy. The finding of a new FRB, which experienced 22 repeating ...

Image: Exceptionally rare triple ring galaxy

The Hubble Classification, also known as the Hubble Sequence, is a widely recognized method for systematically categorizing galaxy morphology. Galaxies are classified into elliptical, lenticular, and spiral (or barred spiral) ...

New report details what happened to the Arecibo Observatory

In 1963, the Arecibo Observatory became operational on the island of Puerto Rico. Measuring 305 meters (~1000 ft) in diameter, Arecibo's spherical reflector dish was the largest radio telescope in the world at the time—a ...
