Astronomers observed a nova explosion for the first time by accident

Astronomers observed a nova explosion for the first time by accident For the first time, a team of scientists have captured all phases of a classical nova explosion — before, during, and after the event.Our sun will most likely become a white dwarf at the end of its life.

Closest exoplanet Proxima b remains mysterious, in the absence of direct observation

Closest exoplanet Proxima b remains mysterious, in the absence of direct observation The best we can do right now is make some educated guesses about conditions on Proxima b.According to researchers at France’s CNRS, there’s at least a possibility that Proxima b has liquid oceans on the surface.

Planet nine might be pulling our solar system out of alignment

Planet nine might be pulling our solar system out of alignment Their observations indicate that planet nine could be causing a “wobble” in the solar system.While we can’t see planet nine, astronomers have detected a number of bizarre effects in the solar system that could be explained by the object.

Astronomers get a chance to watch a rare red nova in its opening strains

Astronomers get a chance to watch a rare red nova in its opening strains As you might suspect, a contact binary is an unstable state of affairs.When that finally happens, the cores of the two stars will merge and then explode as a luminous red nova.

Scientists want you to help them find planets in this database of stars

Scientists want you to help them find planets in this database of stars So now, researchers are hoping that members of the public will use their free time to comb through and find hints of planets circling those alien suns.By checking out these measurements, scientists can actually learn more about how a star wobbles in its orbit.

Scientists observe first planet-induced stellar pulsations

Scientists observe first planet-induced stellar pulsations But researchers now claim to have found the first example of stellar pulsations caused by an exoplanet.The star HAT-P-2 is emitting visible pulses that seem to be a result of a particularly large exoplanet in a highly eccentric orbit.

Listen up: NASA wants to talk about a ‘discovery beyond our solar system’

Listen up: NASA wants to talk about a ‘discovery beyond our solar system’ These planets orbiting stars outside our solar system have fascinated astronomers for decades.The agency said yesterday it will host a news conference on Wednesday to discuss recent discoveries of planets beyond our solar system.

7 planets orbiting a star 39 light-years away could play host to alien life

7 planets orbiting a star 39 light-years away could play host to alien life Scientists have discovered that at least seven Earth-sized worlds circle the star TRAPPIST-1, a ultracool dwarf star only about 40 light-years from Earth.Just like Jupiter's moons, the planets orbiting TRAPPIST-1 all interact with one another, meaning that their orbits are influenced by one another.

The building blocks of life are much more common than we thought

The building blocks of life are much more common than we thought There are six chemical elements common to all known life: carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur.But silicon is such a heavy atom that thermodynamics seems to look sternly upon the idea of silicon-based life.
