A New Technique to Find Cold Gas Streams That Might Make up the Missing (Normal) Matter in the Universe

   10 Feb 00:00:14  |  Universe Today

Where is all the missing matter? That question has plagued astronomers for decades, because the Universe looks emptier than it should, given current theories about its makeup. Most of the Universe (70%) appears to be composed of Dark Energy, the mysterious force which is causing the Universe’s rate of expansion to increase. Another 25% of …

Jupiter?s Trojan Asteroids Offer Surprises Even Before NASA?s Lucy Mission has a Chance to Visit Them.

   09 Feb 00:00:04  |  Universe Today

A new study out this month suggests that Jupiter’s Trojan asteroids may be more peculiar than previously thought. The Trojan asteroids are rocky objects which orbit the Sun just ahead of and just behind the gas giant, in gravitational sweet spots known as Lagrange points. The swarm ahead of Jupiter, known as the L4 (Greek) …

Dark Energy Survey Finds Hundreds of New Gravitational Lenses

   08 Feb 00:00:07  |  Universe Today

It?s relatively rare for a magical object from fantasy stories to have a analog in real life.  A truly functional crystal ball (or palantir) would be useful for everything from military operations to checking up on grandma. While nothing exists to be able to observe the mundanities of everyday life, there is something equivalent for …

A New Radar Instrument Will Try To Fill the Void Left By Arecibo

   06 Feb 00:00:09  |  Universe Today

Observational astronomy is dependent on its data, and therefore also dependent on the instruments that collect that data.  So when one of those instruments fails it is a blow to the profession as a whole.  The collapse of the Arecibo Telescope last year after it was damaged by Hurricane Maria in 2017 permanently deprived the …

Astronomers Can Predict When a Galaxy?s Star Formation Ends Based on the Shape and Size of its Disk

   06 Feb 00:00:09  |  Universe Today

A galaxy’s main business is star formation. And when they’re young, like youth everywhere, they keep themselves busy with it. But galaxies age, evolve, and experience a slow-down in their rate of star formation. Eventually, galaxies cease forming new stars altogether, and astronomers call that quenching. They’ve been studying quenching for decades, yet much about …

Astronomers are now Finding Planetary Disks Around the Smallest, Least Massive Stars

   05 Feb 00:00:14  |  Universe Today

Astronomers have been watching planetary systems form around sun-like stars for decades. And now, new observations with the ALMA telescope reveal the same process playing out around the smallest, but most common, stars in galaxy. The smallest stars in the universe, red dwarf stars, are known to have planetary systems, as shown by the famous …
