The seven members of the Expedition 73 crew welcomed the arrival of a SpaceX resupply ship, worked on science and kept the International Space Station up and running station this week in Earth orbit.

The Celestron SkyMaster binoculars come highly recommended by our experts, and with a saving of over $116, now is the time to spot stars and galaxies for less.

In the sparsely populated Kimberley region of Western Australia, jagged landforms reach like fingers into the turquoise-blue ocean waters. Along the coastline north of Derby, they used to reach even farther. But rising sea levels submerged part of the coastal landscape, giving rise to hundreds of islands and low-lying reefs that compose the Buccaneer Archipelago.

Can we turn to the past to learn more about how interactions between plants and pollinators changed during climate change?

Astronomers may have solved the mystery of how hypervelocity white dwarfs rocket out of the Milky Way at breakneck speeds.

Genetic and anatomical data reveal how the human pelvis acquired its unique shape, enabling our ancestors to walk on two legs

As humans expand into space, how we'll continue to expand the species remains an important question.

There's more to being a Vulcan than prosthetic ears and playing it straight.

The near-Earth asteroid's microscopic surface tells a detailed story.

A survey of Scientific American’s century of quantum coverage helps explain the enduring popularity of strange physics

A star 3,000 light years away pulled off the ultimate disappearing act, dimming by 97% for eight months before mysteriously returning to full brightness. This unexpected vanishing trick has finally been solved by astronomers who discovered a massive dust disk and a hidden companion star orchestrating one of the rarest eclipsing events ever observed, a one in a million phenomenon that won't happen again until 2068.

Stars with eight or more stellar masses are termed high-mass stars. There are questions around how these stars can become so massive, since as they form they lose mass through stellar winds and radiation. New research shows that elongated streams of gas that feed these stars explains their high masses.

For the first time, astrophysicists have spotted a supernova right before it explodes. This is a rare glimpse inside a massive star before it meets its doom. The star was stripped down to its core, and the observations confirm theories that show stars have onion-like layers.
