Is an asteroid from interstellar space really a probe from an alien civilization? Probably not, but Breakthrough Listen wants to find out.
The Deep Sky Network is a collection of radio antenna dishes located in Madrid (Spain), Canberra (Australia) and California in the U.S.
Just when you think you’ve got a mystery solved, new data revives the mystery again.
They aren’t local, they aren’t aliens, and they might help us understand dark matter.
The Wow! signal may have been caused by comets.
When matter accretes around a black hole, some of it is captured, but some of it is pushed away into long jets. In the case of this image, the jets stream out for about 1.5 million light years.
Sometimes astronomical light is reflected from natural sources or emitted by the objects themselves, but sometimes we actively shine light on an object to get an image.
If a typical mobile phone was placed on the surface of Mars, it would be the brightest radio object in the night sky.
One of the more powerful techniques of radio astronomy is the use of interferometry to combine the signals of several radio antennas into a single virtual telescope. Through interferometry we can make radio images with resolutions greater than that of the Hubble telescope. But how does interferometry work?
