Jets and winds from galaxy cores appear to share a common cause

Astronomers have a rough understanding of how galaxies emit jets from their cores. Galaxy cores also blow out winds of ionized gas, for which researchers lack a general explanation. SRON astronomers have now found a correlation ...

Galactic wind provides clues to evolution of galaxies

The Cigar Galaxy (also known as M82) is famous for its extraordinary speed in making new stars, with stars being born 10 times faster than in the Milky Way. Now, data from the Stratospheric Observatory for Infrared Astronomy, ...

In colliding galaxies, a pipsqueak shines bright

In the nearby Whirlpool galaxy and its companion galaxy, M51b, two supermassive black holes heat up and devour surrounding material. These two monsters should be the most luminous X-ray sources in sight, but a new study using ...

A stellar achievement: Magnetized space winds in the laboratory

New insights have been gained about stellar winds, streams of high-speed charged particles called plasma that blow through interstellar space. These winds, created by eruptions from stars or stellar explosions, carry with ...

Cosmic magnetic fields with astonishing order

Turbulent processes in galaxies generate vast magnetic fields that often present a regular structure on a large scale. These are the findings of a study conducted by astronomers at Ruhr-Universität Bochum under the auspices ...

Why is massive star formation quenched in galaxy centers?

The current cosmological model to explain the universe, the "Big Bang" model, aims to describe all observable phenomena, including the evolution of galaxies from earliest times to the present day. One of the major problems ...

Solar minimum is coming

High up in the clear blue noontime sky, the sun appears to be much the same day-in, day-out, year after year.

How bad is the radiation on Mars?

Human exploration of Mars has been ramping up in the past few decades. In addition to the eight active missions on or around the Red Planet, seven more robotic landers, rovers and orbiters are scheduled to be deployed there ...

How much radiation damage do astronauts really suffer in space?

Space is a really inhospitable place to live – there's no breathable air, microgravity wastes away your bones and muscles and you're subjected to increased doses of radiation in the form of high-energy charged particles. ...
