Helium spotted in a comet like exoplanet for the first time

The planet is so close to its host star that the atmosphere is getting ripped off and pushed out, making it look like a comet with a long tail of gases pointing away from the star and it has helium in an excited state, making it possible to spot in the IR wavelength. May 3, 2018
Earth, Magnetic field,

No, the Earth's geomagnetic field is not going to flip, only weaken

The Earth's magnetic field is weakening and this has led scientists to speculate that the field is undergoing a complete reversal. However, previous extreme events and their patterns show that this time, the magnetic field will wobble, but recover without too much harm done. May 1, 2018
Mars Water

New evidence shows lakes on Mars dried up 3.5bn years ago

In early 2017 scientists announced the discovery of possible desiccation cracks in Gale Crater, which was filled by lakes 3.5 billion years ago. Since desiccation mudcracks form only where wet sediment is exposed to air, their position closer to the centre of the lake bed rather than the edge also suggests that lake levels rose and fell dramatically over time.

Watch: Hubble footage of 2 galaxies crashing into each other

Two spiral galaxies, about 80 million light-years away, is crashing into each other in a slow, gradual merger that will last millions of years. This Hubble footage combines visible light with infrared and X-ray wavelengths to offer the best possible view of this slow dance of the cosmos. Apr 24, 2018
