It’s a spectacular achievement to rendezvous with an asteroid as it’s whizzing around the sun. It's even more amazing to collect a sample. That's what the Hayabusa2 spacecraft did in February 2019. Here's what researchers learned.

Italy’s northern border with Switzerland depends on the natural, morphological boundaries of glaciers’ frontiers. But in recent years, glaciers have been melting at increased rates due to climate change. This has caused the border to shift noticeably.

The colossal iceberg from Antarctica’s Larsen-C Ice Shelf finally fractured in April, generating a new 51-square-nautical-mile iceberg.

It's nature with a much-decreased human influence. We've been hearing stories like this from all around the globe. People in India’s northern state of Punjab have reported seeing the Himalayas for the first time in decades. These satellite images over northern India show strikingly how aerosol levels have dropped since the Covid-19 lockdown began.

LIGO and Virgo detectors have now captured the first gravitational waves from a binary black hole merger where the black hole masses are unequal.

The Hubble Space Telescope was launched on April 24, 1990. It's spent the past 3 decades acquiring magnificent images of distant space objects, providing a time machine that's taken astronomers back to when the universe was less than a billion years old.
