ALIEN WATER from beyond our solar system found on interstellar comet ‘Borisov’

The research suggests that Borisov produces up to 19 kilograms of water per second Water from a completely alien star system has been detected on the interstellar comet 2I/Borisov, which is currently passing through our space neighborhood.In an extraordinary breakthrough, astronomers studying Borisov believe they have detected the tell-tale signs of water on the visiting…

Cosmic hide and seek: Can you find the huge black hole lurking in this...

Skip to content M87 first began to draw attention from astronomers back in 1918 Somewhere in this stunning image, strikingly reminiscent of science fiction scenes, lurks an enormous black hole, consuming huge quantities of mass from its surroundings. Can you find it? (Hint: look to the light.)Black holes are incredibly dense with extreme gravity which…

Skip to content The black hole’s extreme gravity skews light emitted by different regions of the disk NASA - September 30, 2019 This new visualization of a black hole illustrates how its gravity distorts our view, warping its surroundings as if seen in a carnival mirror.The visualization simulates the appearance of a black hole where…

Get ready for more interstellar objects, astronomers say

Gregory Laughlin and Malena Rice weren’t exactly surprised a few weeks ago when they learned that a second interstellar object had made its way into our solar system.The Yale University astronomers had just put the finishing touches on a new study suggesting that these strange, icy visitors from other planets are going to keep right…

Comet’s collapsing cliffs and bouncing boulders

Scientists analyzing the treasure trove of images taken by ESA’s Rosetta mission have turned up more evidence for curious bouncing boulders and dramatic cliff collapses.Rosetta operated at Comet 67P/Churyumov-Gerasimenko between August 2014 and September 2016, collecting data on the comet’s dust, gas and plasma environment, its surface characteristics and its interior structure.As part of the…

NASA’s WFIRST will help uncover the universe’s fate

Scientists have discovered that a mysterious pressure dubbed “dark energy” makes up about 68% of the total energy content of the cosmos, but so far we don’t know much more about it. Exploring the nature of dark energy is one of the primary reasons NASA is building the Wide Field Infrared Survey Telescope (WFIRST), a…

‘Pluto is a planet’: NASA official risks sparking science civil war with controversial declaration

One brave NASA administrator is refusing to bow to the prevailing scientific consensus, and is risking potential ostracization or, worse still, online ridicule, for proudly declaring that “Pluto is a planet.”Saturday, August 24, 2019 marked 13 years to the day since Pluto was demoted from having the status of a planet to being assigned that…

Skip to content Most of the dots in this view represent the end points of the life cycle of star This colourful spread of light specks is in fact a record of extremely powerful phenomena taking place in a galaxy known as Messier 83, or M83. Located some 15 million light-years away, M83 is a…

NASA Gets a Rare Look at a Rocky Exoplanet’s Surface

A new study using data from NASA’s Spitzer Space Telescope provides a rare glimpse of conditions on the surface of a rocky planet orbiting a star beyond the Sun. The study, published today in the journal Nature, shows that the planet’s surface may resemble those of Earth’s Moon or Mercury: The planet likely has little…
