Multipurpose laboratory module Nauka will be launched to the International Space Station (ISS) in the autumn of 2020 at the earliest, a source in the space rocket industry told TASS.

Stellar Waltz with Dramatic Ending

Astronomers at the University of Bonn and their colleagues from Moscow have identified an unusual celestial object. It is most likely the product of the fusion of two stars that died a long time ago. After billions of years circling around each other these so-called white dwarfs merged and rose from the dead. In the near future, their lives could finally end - with a huge bang. The researchers are now presenting their findings in the journal Nature.

For the first time, a cross-disciplinary study has shown chemical, physical, and material evidence for water formation on the Moon. Two teams from the University of Hawaii at Manoa collaborated on the project: physical chemists at the UH Manoa Department of Chemistry's W.M. Keck Research Laboratory in Astrochemistry and planetary scientists at the Hawaii Institute of Geophysics and Planetology (HIGP).

Gas Insulation Could Be Protecting an Ocean Inside Pluto

The bright “heart” on Pluto is located near the equator. Its left half is a big basin dubbed Sputnik Planitia. Figures created using images by NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute.

Computer simulations provide compelling evidence that an insulating layer of gas hydrates could keep a subsurface ocean from freezing beneath Pluto’s icy exterior, according to a study published in the journal Nature Geoscience.

Minor Geomagnetic Storm May Hit Earth on Tuesday


A G1-class (minor) geomagnetic storm may hit the Earth on Tuesday, May 21, according to the National Oceanic and Atmospheric Administration (NOAA). The storming is expected when a stream of solar wind, flowing from a hole in the sun’s atmosphere, will reach our planet.

Sedimentary, Dear Johnson: Is NASA Looking at the Wrong Rocks for Clues to Martian Life?

In 2020, NASA and European-Russian missions will look for evidence of past life on Mars. But while volcanic, igneous rock predominates on the Red Planet, virtually the entire Earth fossil record comes from sedimentary rocks.
