Giant Planets Could Form Around Tiny Stars in Just a Few Thousand Years

M-type (red dwarf) stars are cooler, low-mass, low-luminosity objects that make up the vast majority of stars in our Universe – accounting for 85% of stars in the Milky Way galaxy alone. In recent years, these stars have proven to be a treasure trove for exoplanet hunters, with multiple terrestrial (aka. Earth-like) planets confirmed around the Solar System’s nearest red dwarfs.

But what is even more surprising is the fact that some red dwarfs have been found to have planets that are comparable in size and mass to Jupiter orbiting them. A new study conducted by a team of researchers from the University of Central Lancashire (UCLan) has addressed the mystery of how this could be happening. In essence, their work shows that gas giants only take a few thousand years to form.

Rosetta Saw the Building Blocks of Life on Comet 67P

Why is there so little nitrogen in Comet 67P/Churyumov-Gerasimenko (67P)? That’s a question scientists asked themselves when they looked at the data from the ESA’s Rosetta spacecraft. In fact, it’s a question they ask themselves every time they measure the gases in a comet’s coma. When Rosetta visited the comet in 2014, it measured the gases and found that there was very little nitrogen.

In two new papers published in Nature Astronomy, researchers suggest that the nitrogen isn’t really missing at all, it’s just hidden in the building blocks of life.

The Evidence is Leaning More and More Towards an Asteroid Ending the Dinosaurs

Which camp are you in: volcanoes? Or asteroids?

When it comes to the extinction of the dinosaurs, science has whittled it down to those two possibilities. The asteroid strike has been the leading candidate for quite some time now, but those darn volcanoes refuse to stand down.

A new study is presenting even more evidence that it was the impact that wiped out the dinosaurs, and not volcanoes.

China’s 500-Meter FAST Radio Telescope is Now Operational

The world’s largest and most sensitive radio telescope is officially open for business according to Xinhua, China’s official state-run media. The FAST Radio Telescope saw fist light in 2016 but has been undergoing testing and commissioning since then. FAST stands for Five-hundred meter Aperture Spherical Telescope.

SpaceX Crew Dragon Capsule Nails In-Flight Abort Test! Next Stop, the ISS!

At Launch Complex 39A at the Kennedy Space Center in Cape Canaveral, Florida, during the morning hours this past Sunday (Jan, 19th), SpaceX conducted the final uncrewed test of their Crew Dragon space capsule. This was the all-important in-flight abort test, the purpose of which was to validate the crew capsule’s escape capabilities in the event of an unexpected emergency during launch.

The event, which was live-streamed by NASA TV, was a complete success and saw the Crew Dragon successfully separate from its Falcon 9 launcher before being retrieved at sea. With this test complete, NASA and SpaceX will be moving forward with the first crewed mission. Known as Crew Demo-2, this mission will see two astronauts launched aboard the Crew Dragon to the International Space Station (ISS) later this year.

More Mysterious Space Blobs Have Been Found Near the Center of the Milky Way

At the center of our galaxy lies a region where roughly 10 million stars are packed into just 1 parsec (3.25 light-years) of space. At the center of this lies the supermassive black hole (SMBH) known as Sagittarius A*, which has a mass of over 4 million Suns. For decades, astronomers have been trying to get a better look at this region in the hopes of understanding the incredible forces at work and how they have affected the evolution of our galaxy.

What they’ve found includes a series of stars that orbit very closely to Sagittarius A* (like S1 and S2), which have been used to test Einstein’s Theory of General Relativity. And recently, a team from UCLA’s Galactic Center Orbits Initiative detected a series of compact objects that also orbit the SMBH. These objects look like clouds of gas but behave like stars, depending on how close they are in their orbits to Sagittarius A*.

A Mysterious Burst of Gravitational Waves Came From a Region Near Betelgeuse. But There’s Probably No Connection

Gravitational waves are caused by calamitous events in the Universe. Neutron stars that finally merge after circling each other for a long time can create them, and so can two black holes that collide with each other. But sometimes there’s a burst of gravitational waves that doesn’t have a clear cause.
