For people interested in all things beyond Earth, the words methane and Titan go hand in hand. After all, Titan is the only other world in our Solar System where liquid flows over the surface. While trying to understand Titan’s methane cycle, scientists have discovered something else: a bizarre methane ice feature that wraps halfway around Saturn’s largest moon.

Black holes, those beguiling singularities that sit on the precipice of the known and the unknown, keep surprising us with their behaviour. As organizations like the Event Horizon Telescope have made clear, there’s a lot we don’t know about the holes, and worse than that, we don’t even know how much we don’t know.
Now scientists have observed a new phenomenon that adds to the black hole mystique: a rapidly spinning black hole that ejects massive blobs of plasma.

It takes a rich and diverse set of complex molecules for things like stars, galaxies, planets and lifeforms like us to exist. But before humans and all the complex molecules we’re made of could exist, there had to be that first primordial molecule that started a long chain of chemical events that led to everything you see around you today.
Though it’s been long theorized to exist, the lack of observational evidence for that molecule was problematic for scientists. Now they’ve found it and those scientists can rest easy. Their predictive theory wins!

The Cassini mission to Saturn and its moons wrapped up in 2017, when the spacecraft was sent plunging into the gas giant to meet its end. But there’s still a lot of data from the mission to keep scientists busy. A team of scientists working with Cassini data have made a surprising discovery: Titan’s methane-filled lakes are much deeper, and weirder, than expected.

NASA’s new planet-hunting telescope, TESS (Transiting Exoplanet Survey Satellite), just found its first Earth-sized world. Though the Earth-sized planet, and its hot sub-Neptune companion, were first observed by TESS in January 2019, it’s taken until now to confirm their status with ground-based follow-up observations. The discovery is published in The Astrophysical Journal Letters.

The early days of the Solar System are hard to piece together from our vantage point, billions of years after it happened. Now a team of scientists have found a tiny chunk of an ancient comet inside an ancient meteorite. They say it sheds light on the early days of the Solar System when planets were still forming.

Beresheet, the unlikely lander built with donations to a non-profit group, crashed into the Moon. But that doesn’t mean it wasn’t a historic accomplishment in its own way. Now SpaceIL, the non-profit behind Beresheet, wants to send another lander to the Moon.

It’s hard to believe that MSL Curiosity has been on Mars for almost seven years. But it has, and during that time, the rover has explored Gale Crater and Mt. Sharp, the central peak inside the crater. And while it has used its drill multiple times to take rock samples, this is the first sample it’s gathered from the so-called ‘clay unit.’

Engineers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) are busy working with a replica InSight Lander to see if they can understand what’s blocking the lander’s mole.
The mole is the short name for the lander’s Heat Probe, which is hammering its way into the Martian surface. The Heat Probe is actually called the HP3, or Heat and Physical Properties Package. It’s designed to work it’s way as far as 5 meters (16.4 ft.) into the soil, where it will measure the heat flowing from the interior of the planet. Those measurements will tell scientists a lot about the structure of Mars, and how rocky planets formed.
But as reported last month, the probe is being blocked at about 30 cm (1 ft.)

The Israeli Beresheet spacecraft has crashed into the Moon. The craft, whose name is Hebrew for “in the beginning” made its descent to the Moon but failed to stick its landing. If it had been successful, it would have put Israel in elite company, and made them only the fourth country to have a soft landing on the Moon, joining the USA, China, and the former Soviet Union.
