An international team of astronomers, with researchers at Leiden Observatory playing a leading role, has mapped the fuel for galaxy formation in the iconic Hubble Ultra Deep Field. The results of the research have been accepted ...

NASA chief warns Congress about Chinese space station

NASA chief Jim Bridenstine told lawmakers Wednesday it was crucial for the US to maintain a presence in Earth's orbit after the International Space Station is decommissioned so that China does not gain a strategic advantage.

Could life exist deep underground on Mars?

Recent science missions and results are bringing the search for life closer to home, and scientists at the Center for Astrophysics | Harvard & Smithsonian (CfA) and the Florida Institute of Technology (FIT) may have figured ...

New analysis of black hole reveals a wobbling shadow

In 2019, the Event Horizon Telescope Collaboration delivered the first image of a black hole, revealing M87*—the supermassive object in the center of the M87 galaxy. The team has now used the lessons learned last year to ...

Indian astronomers discover 70 new variable stars

Astronomers from India have conducted a long-term photometric variability survey of an open cluster known as NGC 559. As a result, they detected 70 new variable stars in the field of this cluster. The finding is presented ...

ISS moves to avoid space debris

Astronauts on the International Space Station carried out an "avoidance maneuver" Tuesday to ensure they would not be hit by a piece of debris, said US space agency NASA, urging better management of objects in Earth's orbit.

School bus-size asteroid to safely zoom past Earth

A small near-Earth asteroid (or NEA) will briefly visit Earth's neighborhood on Thursday, Sept. 24, zooming past at a distance of about 13,000 miles (22,000 kilometers) above our planet's surface. The asteroid will make its ...

MoonRanger will search for water at moon's south pole

MoonRanger, a small robotic rover being developed by Carnegie Mellon University and its spinoff Astrobotic, has completed its preliminary design review in preparation for a 2022 mission to search for signs of water at the ...

Space nematodes: A giant leap for interplanetary agriculture

In a successful return-to-space mission, research study results indicate that beneficial insect-killing nematodes (small round worms) can be used in the future for natural control of insect pests when humans are growing crops ...
