Hubble captures movie of DART asteroid impact debris

The NASA/ESA Hubble Space Telescope captured a series of photos of rapid changes to the asteroid Dimorphos when it was deliberately hit by a 545-kilogram spacecraft on 26 September 2022. The primary objective of the NASA mission, called DART (Double Asteroid Redirection Test), was to test our ability to alter the asteroid’s trajectory as it orbits its larger companion asteroid, Didymos. Though Dimorphos poses no threat to Earth, data from the mission could help inform researchers how to potentially change an asteroid’s path away from Earth, if ever necessary.

Humanity has Never Seen the sky in the Longest Wavelengths. That Could Change With a new Space Telescope

Technological revolutions can bring about dramatic changes in various fields, some of which are only tangentially related to the field being disrupted. Occasionally, a few technological revolutions happen simultaneously, enabling concepts that would have been impossible without any of them. Such revolutions are currently happening in the space industry. With rockets more massive than ever coming online, and mega-constellations of satellites roaming our skies, there is plenty of disruption going on. Now a team from MIT hopes to use those technologies to look at an area of astronomy that has never been seen before – low-frequency radio astronomy.
