Image: Hubble captures a cluster in the Large Magellanic Cloud

This striking Hubble Space Telescope image shows the densely packed globular cluster known as NGC 2210, which is situated in the Large Magellanic Cloud (LMC). The LMC lies about 157,000 light-years from Earth and is a so-called ...

New dark matter theory explains two puzzles in astrophysics

Thought to make up 85% of matter in the universe, dark matter is nonluminous and its nature is not well understood. While normal matter absorbs, reflects, and emits light, dark matter cannot be seen directly, making it harder ...

Four eruptive young stellar objects discovered

By analyzing the data from the SPICY catalog and from NASA's WISE spacecraft, an international team of astronomers has discovered four new eruptive young stellar objects (YSOs). The finding was presented in a research paper ...

To the moo-n: Cow dung fuels Japan's space ambitions

Japan's space industry opened potentially an udder-ly new chapter on Thursday with a start-up testing a prototype rocket engine that runs on fuel derived purely from a plentiful local source: cow dung.

Famed Halley's comet passes aphelion this weekend

It's lonely out there in the frozen outer solar system. On Saturday, December 9th, that most famous of all comets 1P/Halley reaches a hallmark point on its 75-year journey through the solar system, reaching aphelion or its ...

Measuring the distances to galaxies with space telescopes

One of the James Webb Space Telescope's science goals is to understand how galaxies in the early universe formed and evolved into much larger galaxies like our own Milky Way. This goal requires that we identify samples of ...

Communicating with a relativistic spacecraft gets pretty weird

Someday, in the not-too-distant future, humans may send robotic probes to explore nearby star systems. These robot explorers will likely take the form of lightsails and wafercraft (a la Breakthrough Starshot) that will rely ...

Video: Tracking human emissions from space

The Copernicus Anthropogenic Carbon Dioxide Monitoring (CO2M) mission will be the first satellite mission to measure how much carbon dioxide is released into the atmosphere through human activity.

PACE testing and preparation continues for launch in early 2024

Engineers are executing a comprehensive performance test to ensure the PACE spacecraft is ready for launch. NASA's Plankton, Aerosol, Cloud ocean Ecosystem (PACE) mission will study what makes Earth so different from every ...
