Planet-sized space weather explosions at Venus

more »

Researchers recently discovered that a common space weather phenomenon on the outskirts of Earth's magnetic bubble, the magnetosphere, has much larger repercussions for Venus. The giant explosions, called hot flow anomalies, can be so large at Venus that they're bigger than the entire planet and they can happen multiple times a day.

The Long Jet of the Lighthouse Nebula

more »

The Lighthouse nebula was formed by the wind of a pulsar, a rapidly rotating, magnetized neutron star, as it speeds through the interstellar medium at over 1,000 kilometers per second. Some 23,000 light-years distant toward the southern constellation Carina, pulsar and wind nebula (cataloged as IGR J1104-6103) are indicated at the lower right in this remarkable image from the Chandra X-ray Observatory. Energetic particles generated by the pulsar are swept back into the wind's comet-like tail trailing up and to the left, along the direction of the pulsar's motion away from its parent supernova remnant. Both runaway pulsar and expanding remnant debris field are the aftermath of the core-collapse-explosion of a massive star, with the pulsar kicked out by the supernova explosion. Adding to the scene of exotic cosmic extremes is a long, spiraling jet extending for almost 37 light-years, but nearly at a right angle to the pulsar's motion. The high-energy particle jet is the longest known for any object in our Milky Way galaxy.

Astronomers find solar storms behave like supernovae

more »

Researchers have studied the behavior of the Sun's coronal mass ejections, explaining for the first time the details of how these huge eruptions behave as they fall back onto the Sun's surface. In the process, they have discovered that coronal mass ejections have a surprising twin in the depths of space: the tendrils of gas in the Crab Nebula, which lie 6500 light-years away and are millions of times larger.

Remote Antarctic telescope reveals gas cloud where stars are born

more »

Using a telescope installed at the driest place on earth -- Ridge A in Antarctica -- astronomers have identified a giant gas cloud in our galaxy which appears to be in an early stage of formation. Giant clouds of molecular gas are the birthplaces of stars. The newly discovered gas cloud is about 200 light years in extent and ten light years across, with a mass about 50,000 times that of our sun.

Rocks around the clock: Asteroids pound tiny star

more »

Scientists have found evidence that a tiny star called PSR J0738-4042 is being pounded by asteroids -- large lumps of rock from space. The environment around this star is especially harsh, full of radiation and violent winds of particles.

Space eye with 34 telescopes will investigate one million stars

more »

The exploration of planets around stars other than the Sun, known as extrasolar planets or ‘exoplanets’, is one of the most exciting topics of 21st century science. One of the key goals of this research is to discover and learn the properties of Earth-like worlds in the Sun’s neighbourhood. The European Space Agency will do this in preparing a new space mission named PLATO.
