Astronomers have discovered a new type of alien world the first known “ultrahot Neptune,” a giant planet that orbits its star 60 times closer than Earth does the sun, a new study finds.
Previous research found that about 1 in 200 sunlike stars possesses a planet that circles its star so tightly that it orbits in less than one Earth day. Astronomers call these worlds “ultra-short-period planets.” (In contrast, Earth takes slightly more than 365 days to circle the sun; Mercury, our sun’s closest …

Voyager Spacecraft Detect an Increase in The Density of Space Outside The Solar System – ScienceAlert

In November 2018, after an epic, 41-year voyage, Voyager 2 finally crossed the boundary that marked the limit of the Sun’s influence and entered interstellar space. But the little probe’s mission isn’t done yet – it’s now sending home information about the space beyond the Solar System.
And it’s revealing something surprising. As Voyager 2 moves farther and farther from the Sun, the density of space is increasing.
It’s not the first time this density increase has been detected. Voyager 1, whic…
Ice Melt in Alaska Threatens to Unleash Unprecedented ‘Mega-Tsunami’, Scientists Warn – ScienceAlert

A giant, catastrophic tsunami in Alaska triggered by a landslide of rock left unstable after glacier melting is likely to occur in the next two decades, scientists fear – and it could happen within the next 12 months.
A group of scientists warned of the prospects of this impending disaster in Prince William Sound in an open letter to the Alaska Department of Natural Resources (ADNR) in May.
While the potential risks of such a landslide are very serious, there remain a lot of unknowns about jus…
