This NASA illustration photo shows stars that are forming in a dwarf starburst galaxy.

A 22-year-old  university student from Australia has solved a problem which has puzzled astrophysicists for decades, discovering part of the so-called “missing mass” of the universe during her summer break.

The Search is On for a Giant New Planet Hiding on the Outer Edge of Our Solar System

Researchers propose new planet “Tyche” on distant fringe of solar system.

If you grew up thinking there were nine planets and were shocked when Pluto was demoted five years ago, get ready for another surprise. There may be nine after all, and Jupiter may not be the largest.

Fascinating Video of Our Terrifyingly Crowded Solar System

crowded solar system

This image shows the number of asteroids in the solar system currently (2010).

It’s not just our country that’s a little over-crowded – our whole solar system is too.  A fascinating color-coded video illustrates how we have become increasingly aware of the number of asteroids flying close to Earth as telescopes improve. (Pics and video)

Towards Other Earths: 32 New Exoplanets Found

091019105304-large

One of the 32 new exoplanets recently discovered using the HARPS spectrograph is surrounding the star Gliese 667 C, which belongs to a triple system. The 6 Earth-mass exoplanet circulates around its low-mass host star at a distance equal to only 1/20th of the Earth-Sun distance. The host star is a companion to two other low-mass stars, which are seen here in the distance.

Today, at an international ESO/CAUP exoplanet conference in Porto, the team who built the High Accuracy Radial Velocity Planet Searcher, better known as HARPS, the spectrograph for ESO’s 3.6-metre telescope, reports on the incredible discovery of some 32 new exoplanets, cementing HARPS’s position as the world’s foremost exoplanet hunter. This result also increases the number of known low-mass planets by an impressive 30%. Over the past five years HARPS has spotted more than 75 of the roughly 400 or so exoplanets now known.

The Messier 87 galaxy.

An unprecedented measuring campaign has succeeded in precisely defining the place of origin of high-energy gamma radiation in the galaxy Messier 87. This radiation can only be produced by accelerating elementary particles to very high energies in enormous cosmic objects. Now the underlying extreme physical processes and inherent implications can be investigated in more detail.

For people all across the country summer nights are spent in the back yard looking at the stars. Backyard stargazing in the warmer states really picks up when summer is winding down and the heat isn’t so bad and the bugs are starting to thin out. The challenge for many when looking at the night sky is actually finding something worth looking at.
