The "hell planet" where it rains lava

55 Cancri e is a rocky world about eight times the size of Earth. It is the type of exoplanet  known as a "super Earth." Despite its ample size, nothing is "super" about the living conditions here.

Often nicknamed the "hell planet," 55 Cancri e is completely covered in flowing seas of lava, and it may even rain lava there as well. The exoplanet is located 41 light-years from Earth, making it a popular target for studies.

There are no little green men on this lava covered planet.

Signals from exotic new stars could hide in gravitational wave data

A computer simulation suggests that some collisions between exotic, hypothetical stars would make space-time ripple with detectable waves.

What do you think about strange noises coming from space?

“Gravitational wave signals that seem to emanate from black hole collisions may actually come from the clashes of odd, exotic stars – which have been theorised but may or may not exist. If they do, then physicists will have to rethink their standard theories of gravity and particles.

For almost 60 years, researchers have been thinking up cosmic objects that may be possible if there is more to gravity than is suggested by Albert Einstein.”

Space is wonderful. We can not understand  why God made the universe like that. He knows where all the noises we hear are coming from.

Planet spotted orbiting Barnard's star just 6 light years away

Astronomers have detected an exoplanet around Barnard’s star, one of the sun’s closest neighbours, but it is too hot for liquid water or life.

Life in a nearby planet?  

One of the sun’s closest neighbours, Barnard’s star, appears to have at least one planet orbiting it, as well as another three possible planets that need further confirmation.

Astronomers have been looking for planets aroud and Barnard’s star, which at 5.96 light years away is the next-closest star to us after the three stars in the Alpha Centauri system, since the 1960s.

In 2018, researchers claimed to have found a planet that was at least three times larger than Earth, which they called Barnard’s star b, but a follow-up analysis showed that the signals of the apparent planet were actually caused by higher than expected stellar activity.

Now, Jonay Hernández at the Canary Islands Institute of Astrophysics and his colleagues say they have found a new Barnard’s star b, which is around 40 per cent as massive as Earth.

The planet is much closer to its star than any planets in our solar system, completing an orbit in just over three Earth days. This also means its surface is too hot for liquid water or life, with a temperature of around 125°C (257°F).

So the scientist are are claiming that the planet is too hot for liquid water and life.
