Earlier this month, Roger Penrose, Reinhard Genzel, and Andrea Ghez split the 2020 physics Nobel Prize for decades of work on black holes. Click here to learn more about their monumental achievement and about the history of our understanding of these exotic objects in space.

About two thousand years from now, Gamma Cephei, an inconspicuous star in the constellation Cepheus, will become our North Star.

The sun’s second planet, Venus, as seen from the BepiColombo spacecraft as it passed on its way to the innermost planet, Mercury, earlier this month.
Rather than completely disappear – even when vaccines become available- it’s likely that the coronavirus SARS-CoV-2 will be added to the family of infectious diseases known as “endemic” in the human population.

According to new research, the red supergiant star Betelgeuse – which began to dim dramatically in brightness in late 2019 – might not explode for another 100,000 years. The star is also smaller and closer to us than first thought.

In Northern Hemisphere autumn (Southern Hemisphere spring), you can see a group of constellations that represented an “ocean” to the early stargazers.
The constellations visible in the south during the Northern Hemisphere autumn months (overhead on springs evenings for the Southern Hemisphere) constitute a celestial sea. In 2020, the planets Mars, Jupiter and Saturn are bright in this region of the sky.
Alpheratz, the brightest star in the constellation Andromeda, can help you locate the Andromeda Galaxy, the closest large spiral galaxy to our Milky Way home galaxy.
The star Alpheratz is part of the famous star pattern known as the Great Square of Pegasus. It connects Pegasus to the constellation Andromeda. People often find the Andromeda galaxy by star-hopping from Alpheratz - to Mirach and Mu Andromedae - to the galaxy.
Take a video tour of asteroid Bennu’s remarkable terrain and read a list of 10 cool things scientists know about this pristine remnant from the early days of our solar system.
This mosaic image of asteroid Bennu is composed of 12 PolyCam images collected on Dec. 2, 2018 by the OSIRIS-REx spacecraft from a range of 15 miles (24 km). Image via NASA/Goddard/University of Arizona https://www.nasa.gov/feature/goddard/2020/bennu-top-ten
Planetary systems with both super-Earths and Jupiter-type planets may be common, according to a new study. As in our own solar system, the giant planets would act as “bodyguards” protecting the smaller planets from asteroid impacts.
