Large radio bubble detected in galaxy NGC 4217

An international team of astronomers has performed radio observations of a star-forming galaxy known as NGC 4217. The observational campaign detected a large radio bubble in the galaxy's halo. The finding was reported in ...

Gravitational lens confirms the Hubble tension

We've known the universe is expanding for a long time. The first solid paper demonstrating cosmic expansion was published by Edwin Hubble in 1929, based on observations made by Vesto Slipher, Milton Humason, and Henrietta ...

The sun unleashes its strongest flare this cycle

Yesterday the sun released a huge solar flare, and it's heading toward Earth. It's nothing to worry about since it's nowhere near as large as the Carrington Event of 1859, but it is large enough to give us some amazing aurora.

What's the best material for a lunar tower?

Physical infrastructure on the moon will be critical to any long-term human presence there as both America and China gear up for a sustained human lunar presence. Increasingly, a self-deploying tower is one of the most essential ...

Hubble observes a peculiar galaxy shape

This NASA/ESA Hubble Space Telescope image reveals the galaxy, NGC 4694. Most galaxies fall into one of two basic types. Spiral galaxies are young and energetic, filled with the gas needed to form new stars and sporting spiral ...

Mercury's magnetic landscape mapped in 30 minutes

As BepiColombo sped past Mercury during its June 2023 flyby, it encountered a variety of features in the tiny planet's magnetic field. These measurements provide a tantalizing taste of the mysteries that the mission is set ...
