Star nurseries. Planets. Supernova remnants. Here’s a look at some of this year’s stellar JWST images. And the mission is still just getting started.

Astronomers are moving ahead in planning NASA’s Habitable Worlds Observatory, a telescope designed to answer the ultimate question: Are we alone in the universe?

BALTIMORE — In many ways, the conference underway this week at the Space Telescope Science Institute in Baltimore is more like a celebration. About one year into the science mission for the James Webb Space Telescope, the historic observatory is largely an awe-inspiring success. Take, for instance, Marcia Rieke, the principal investigator in charge of the near-infrared camera aboard the ...

This image shows the massive galaxy cluster MACS J1149.5+223, whose light has taken more than 5 billion years to reach us. The cluster's massive mass

This week, we take a look at Singularity Hub's most-read articles of 2021. Despite it all, science and technology continued to move forward this year.

A major report outlining the highest priorities and recommendations for U.S. astronomy has finally been released, revealing the shape of things to come

Scientists analyzed data obtained by NASA’s New Horizons mission to Pluto and the Kuiper Belt and their results were rather surprising – there are a lot fewer galaxies in the universe than previously thought. It was previously stated that there are about 2 trillion galaxies in the universe but new research has revealed that there... Read more »

In the past few decades, it has become part of astronomical lore that at the center of every galaxy lurks a giant black hole into which the equivalent of millions or even billions of suns have disappeared.

The universe may be a little darker after a recent discovery has shown that there could be fewer galaxies populating it.

How Many Galaxies Are in the Universe? A New Answer From the Darkest Sky Ever Observed 3,650 Ordinarily, we point telescopes at some object we want to see in greater detail. In the 1990s astronomers did the opposite. They pointed the most powerful telescope in history, the Hubble Space Telescope, at a dark patch of sky devoid of known stars, gas, or galaxies. But in that sliver of nothingness, Hubble revealed a breathtaking sight: The void was brimming with galaxies. Astronomers have long wonde...
