Image: Hubble spots a swarm of stars

This image from the NASA/ESA Hubble Space Telescope shows a dwarf galaxy named UGC 685. Such galaxies are small and contain just a tiny fraction of the number of stars in a galaxy like the Milky Way. Dwarf galaxies often ...

New research explores the mechanics of how birds flock

Wildlife researchers have long tried to understand why birds fly in flocks and how different types of flocks work. A new study from the University of North Carolina at Chapel Hill explores the mechanics and benefits of the ...

Suppressed star formation in the early universe

Massive clusters of galaxies, some with more mass than a hundred Milky Way galaxies, have been detected from cosmic epochs as early as about three billion years after the big bang. Their ongoing star formation makes them ...

Image: Hubble finds smiling face in a hunt for newborn stars

This image, taken with the NASA/ESA Hubble Space Telescope's Wide Field Camera 3 (WFC3), shows a patch of space filled with galaxies of all shapes, colors and sizes, many of which belong to the galaxy cluster SDSS J0952+3434.

Trees at nighttime trigger formation of charged particles

Understanding how climate has changed over the last centuries and will evolve in the future requires a detailed knowledge of all the climate system components, including an accurate evaluation of the effect of human activity ...

Stars are born in loose groupings

Based on previously published data from the Gaia Mission, researchers at Heidelberg University have derived the conditions under which stars form. The Gaia satellite is measuring the three-dimensional positions and motions ...
