Tabby's Star is dimming again, and two new studies have been released that offer new and interesting theories on what could be causing it.

In the space of just 3 days, a pair of NASA astronauts conducted an unplanned and rapidly executed contingency space walk on the exterior of the space station on Tuesday, May 23 in order to replace a critical computer unit that failed over the weekend.

Under the right conditions, two colliding rocky bodies might form a temporary structure called a 'synestia'. This rotating mass of partially vaporized rock would might only last a hundred years or so.

The "ice giant" Neptune, the farthest planet from our Sun, is made up of gases, super-heated liquids, and maybe even diamonds!

A new study by an international team of researchers has revealed information about the surface conditions on TRAPPIST-1's outermost planet.

In a presentation at Breakthrough Discuss, astrophysicist Dr. Berdyugina explained how methods used to study stars could be used to determine the presence of plants on other planets.

A new study by a team of researchers from Monash University argues that gravitational waves may permanently alter the fabric of spacetime.

KENNEDY SPACE CENTER VISITOR COMPLEX, FL - In a moving ceremony, a pair of veteran NASA astronauts - Michael Foale and Ellen Ochoa - who once flew together on a space shuttle mission, were inducted into the U. S. Astronaut Hall of Fame at the Kennedy Space Center Visitor Complex, Florida, on May 19.

In a special two part episode, Fraser collaborates with space historian Amy Shira Teitel at Vintage Space to investigate what spaceflight advances could have happened. Amy looks at the lost Apollo Missions, while Fraser talks about Werner Von Braun's "Mars Project".

Located in the direction of the Orion constellation, roughly 1600 light-years from Earth, is the diffuse nebula known as the De Marian's Nebula

KENNEDY SPACE CENTER, FL - The worlds emerging 'Digital Society' gained a big boost following SpaceX's stunningly beautiful twilight launch of a Falcon 9 that successfully delivered the huge 6.7 ton mobile Inmarsat-5 F4 broadband satellite to orbit for London-based Inmarsat on Monday, May 15.

We know there's dark matter, and there are galaxies, but are there galaxies entirely made up of dark matter? Astronomer Sarah Pearson joins Fraser to talk about what's out there.

The mysterious star that was found to be dimming in 2015 (prompting speculation about an alien megastucture) has been spotted dimming again!

A team of bioengineering students from UC San Diego has successfully created an experiment to test if beer can be brewed on the Moon

Two studies conducted independently of each other (using data obtained aboard the ISS) have provided a possible glimpse of dark matter
