Four tiny planets are orbiting one of our nearest stars
Astronomers have revealed new evidence that not just one, but four tiny planets are circling around Barnard's Star, the second-nearest star system to Earth.

Astronomers Detect Radio Signals Coming Directly From an Exoplanet For The First Time
There's no proof of other life beyond Earth yet, but scientists are constantly looking out and listening for signs that we're not actually alone in the Universe.

'Black Widow' Exoplanet
A Black Widow exoplanet is a world being slowly evaporated by intense radiation from a pulsar host star, often resulting in a distorted, lemon-like shape and a carbon-rich atmosphere where it may rain...

First radio waves seen from an exoplanet hint at otherworldly auroras
For the first time, scientists have spotted radio waves from an exoplanet. Astronomer Yvette Cendes knows what you’re thinking: “When people see ‘radio signal from an exoplanet,’ they think aliens,” she says. But, sorry — it’s not aliens. Instead, it could be the first clear evidence of an aurora on a planet outside the solar system, Cendes and colleagues report in a paper submitted September 15 to arXiv.org. The radio waves also reveal the planet’s magnetic field, making this potentially the first direct detection of the magnetic field of an exoplanet. “This result, if it holds up in peer review, is an incredibly exciting advancement,” says astronomer Joe Callingham of the University of Amsterdam, who was not involved with the research. “It would be a fantastic result.” Using the MeerKAT radio telescope in South Africa, scientists observed radio waves from Beta Pictoris b, a gas giant orbiting a young star about 63 light-years away. Importantly, the researchers were able to trace those radio waves to the exoplanet itself, rather than the star that it orbits. “We can rule out the star, and … we can say that it’s from this one particular planet,” says Cendes, of the University of Oregon...

A 'rebellious' exoplanet orbits in the opposite direction of its star
A star and its planets form when a cloud of gas and dust collapses in on itself somewhere in space. The cloud then forms a disk around the nascent star, within which the planets will form. This protostar and its disk then rotate in the same direction.
