Hubble sees nearby asteroids photobombing distant galaxies

Some of our solar system's asteroids have photobombed deep images of the universe taken by NASA's Hubble Space Telescope. These asteroids reside, on average, only about 99.4 million km (160 million miles) from Earth — right around the corner in...

ALMA discovers cold dust around nearest star

The ALMA Observatory in Chile has detected dust around the closest star to the Solar System, Proxima Centauri. These new observations reveal the glow coming from cold dust in a region between one to four times as far from Proxima Centauri as the Earth is from the...

Intergalactic plasma filaments confirmed?

On the Space News series, a clear picture of cosmic scale phenomena has emerged: networks of filaments pervade space and are closely linked to the formation and evolution of stars and galaxies. The electric universe and plasma cosmology have always predicted that...

New research looks at how ‘cosmic web’ of filaments alters star formation in galaxies

Astronomer Gregory Rudnick sees the universe crisscrossed by something like an interstellar superhighway system. Filaments — the strands of aggregated matter that stretch millions of light years across the universe to connect galaxy clusters — are the...

Night sky guide for November 2017

November brings us peaks of 2 notable meteor showers, Northern Taurids (Class II) on November 11 and Leonids (Class I) on November 18. The Moon will be 24 days old during the peak of Taurids and 30 during Leonids, presenting minimal interference. We also have peaks...

Saturn's radiation belts: A stranger to the solar wind

The high energy proton population in the environment of Saturn develops independently of the solar wind - and thus in a considerably different way from the one on Earth. The radiation belts of Earth and Saturn differ more strongly than previously assumed. In these...

'Monster' planet discovery challenges formation theory

A giant planet - the existence of which was previously thought extremely unlikely - has been discovered by an international collaboration of astronomers, with the University of Warwick taking a leading role. New research, led by Dr. Daniel Bayliss and Professor...

Spitzer reveals ancient galaxies' frenzied starmaking

A deep look back to the early universe by NASA's Spitzer Space Telescope has revealed a surprisingly rowdy bunch of galaxies. Within a large galaxy sample, Spitzer witnessed around 15% of galaxies undergoing bouts of extreme starmaking, called starbursts. The...

Surprisingly erratic X-ray auroras discovered at Jupiter

ESA and NASA space telescopes have revealed that, unlike Earth’s polar lights, the intense auroras seen at Jupiter’s poles unexpectedly behave independently of one another. Auroras have been seen in many places, from planets and moons to stars, brown...

Jets of ionospheric cold plasma discovered at the magnetopause

The Sun and Earth both produce powerful magnetic fields, and their intersection develops a complex system of physics that determines the space weather experienced by our planet. The solar wind - a constant stream of charged particles (plasma) emitted from the Sun -...

Sentinel-1 sees through hurricanes, helping predict their paths

This year’s Atlantic hurricane season has been a harsh reminder of the grief and devastation brought by these vast storms. Imaging the top of hurricanes from space is nothing new, but the Sentinel-1 satellites can see right through these towering spinning...
