"The Xuntian telescope has been the most important scientific project since the launch of our country's space station program."

The Wide Field Survey Telescope is the largest facility of its kind in the Northern Hemisphere.

A new investigation with NASA’s James Webb Space Telescope into K2-18 b, an exoplanet 8.6 times as massive as Earth, has revealed the presence of

This gas giant regularly absorbs hits from comets and asteroids, protecting inner solar system worlds.

Something remarkable happens when this small sun zooms past its larger companion.

How fast is the Universe expanding? Two major methods disagree. New JWST data, just released, strengthens this Hubble tension even further.

Galaxies are vast swarms of billions of stars along with huge interstellar clouds of gas and dust. A spiral galaxy has a broad, thin disk shape, with a bulge of stars in its core, Within the disk are winding arms of dark dust lanes and bright star-forming regions, This structure is stable when left alone, but is relatively easily disturbed when another galaxy passes near. Astronomers have studied galaxy interactions for decades, and Hubble's keen vision has been particularly useful for examining new details.<br> A 2008 Hubble press release unveiled 59 images of galaxy interactions. Each image, however, captures only one moment in a billion-year-long collision process. This visualization of a galaxy collision supercomputer simulation shows the entire collision sequence, and compares the different stages of the collision to different interacting galaxy pairs observed by Hubble. The two spiral galaxies in the simulation distort, twist, and merge together, matching different images at different times and different viewing angles. With this combination of research simulations and high resolution observations, these titanic crashes can be better illustrated and understood.

Two fundamentally different ways of measuring the expanding Universe disagree. What's the root cause of this Hubble tension?
