Asteroids on a collision course with Earth could be rerouted by spray painting them with a thin layer of paint, a Texas A&M University professor says. Dave Hyland, an aerospace and physics professor at Texas A&M, says an asteroid...

NASA is ready to launch a spacecraft that will smash into a big asteroid to make it change its course.

Astronomers seem to have revealed a puzzling detail in the way dark matter behaves.

They found small, dense concentrations of dark matter that bend and magnify light much more strongly than...

Why is everything within 250 million light years being pulled towards the Great Attractor?

The idea of conservation of momentum can be used to work out what will happen when things collide. Conservation of momentum states that the total momentum of a closed system is constant. This means that the total momentum before a...

Episode 3: Time Machines – Hubble has looked back billions of years in time to see some of the earliest galaxies in their infancy, and it has fundamentally changed what we...

The Hubble Space Telescope has been answering questions about the universe for over 30 years.



The question is: How big is the Hubble Space Telescope? You might be...

Late last year, astronomers noticed that an asteroid named Scheila had unexpectedly brightened and it was sporting short-lived plumes. Data from NASA's Swift satellite and Hubble Space Telescope show that these changes...
