Astronomers Observe Exploding Star for the First Time

For the first time ever, astronomers have recorded the moment at which a star started to explode – known as the “shock breakout” – within the optical wavelength of NASA’s Kepler space telescope.

The astronomy team, led by Peter Garnavich, Professor of Astrophysics at the University of Notre Dame in Indiana, USA, monitored the light levels emitted by sources within 500 galaxies – around 500 trillion stars – over a three-year period in order to detect the early signs of a supernova. The observations led to Kepler monitoring two stars in particular – both red supergiants – that were on the verge of exploding. The massive stellar bodies, KSN 2011a and KSN 2011d, were around 1.2 billion light years away.

“To put their size into perspective, Earth’s orbit about our sun would fit comfortably within these colossal stars,” Garnavich explained on the NASA website.

KSN 2011a and KSN 2011d were then observed exploding. While the Type II supernovae of both stars matched known mathematical models of the phenomena, the explosion KSN 2011a was not preceded by the expected shock breakout.

“In order to see something that happens on timescales of minutes, like a shock breakout, you want to have a camera continuously monitoring the sky,” Garnavich said. “You don’t know when a supernova is going to go off, and Kepler’s vigilance allowed us to be a witness as the explosion began.”

The video below shows KSN 2011d exhibiting the shock breakout prior to its supernova:

“That is the puzzle of these results,” Garnavich added. “You look at two supernovae and see two different things. That’s maximum diversity.”

Find out How to Get Access to Supernova’s Closed Beta

Have you wanted to try a new MOBA for a change? Well, now you can. If you like MOBA and got fed up of League of Legends and Dota 2, you know have the chance to try out a new sci-fi MOBA title called Supernova. From the looks of it, it has a potential, while also breaking away from all the mystical magic you see in the well-known MOBA games today. Take a look at how NVIDIA describes the title on their blog.

It is mankind’s distant, space-faring future. Having tamed their own solar system, the human race has ventured forth into the cosmos to find a universe in peril. Ancient and mysterious portals have brought humanity face to face with vast, unrelenting alien legions, set to wage war across the galaxy. In this time of universal chaos, human and alien races alike must rely on their most skilled commanders to lead their forces in the fight for galactic dominance while uncovering the secrets behind the strange portals.

It looks like the title is made by Bandai Namco in collaboration with Primal Game Studios and they are offering GeForce owners a chance to get one of their closed beta keys to try the game before it hits open beta. So stop thinking about it and head on over to NVIDIA’s website and get one today! AMD owners can also have a chance to sign up for the beta on the game’s website. More information about the game and how to sign up can be found on their official page here.

EVGA Released New Models in the SuperNOVA G2 Line-Up

It has been three months by now since EVGA first introduced us to these two new power supply models, the EVGA SuperNova 650 G2 and Supernova 550 G2, and now they’re finally become available too.

These power supplies are based on the award winning G2 power supplies and feature an 80 Plus gold certification on the efficiency to provide clean power to all your components.

The CO Control Fan system offers fan modes to provide you with an absolute zero fan noise setup, when it isn’t needed. This means that no fan is spinning unless it’s needed and that’s just as wonderful on PSUs as it is on graphics cards.

The Supernova 650 G2 and Supernova 550 G2 are both backed by a 7-year warranty and they are built with 100% Japanese capacitors to make sure it easily lasts that time.

The PSUs are fully modular, allow for crossfire or SLI setups and come with all the protections you’ll want. OVP, UVP, OCP, OPP, and SCP are all included.

When a company sais that a product is available, it effectively means that it is on its way to the distributors who will then send it on to the shops where you can buy them. So while you might not be able to find it at your favorite shop yet, you should very soon.

EVGA Introduced SuperNOVA 650 GS and 550 GS Power Supplies

EVGA has introduced the two new power supplies to their award-winning GS lineup, the SuperNOVA 650 GS and 550 GS, and they’re said to come at a more affordable price. The new PSUs offer great performance with their 80 Plus Gold certification and completely silent operation under low loads as well a being completely modular.

The PSUs are built with high-quality Japanese capacitors to provide the 80 PLUS Gold certification with 90% (115VAC) / 92% (220VAC~240VAC) efficiency or higher under typical loads. That coupled with the low noise generation of the Teflon Nano-Steel Bearing fans could make them a great choice.

They are also fully Modular to reduce cable clutter in your case and improve the airflow. Of course the PSUs are ready for both NVIDIA SLI & AMD Crossfire setups and feature the ECO mode button that also could be labeled silent mode instead. The protections include OVP (Over Voltage Protection), UVP (Under Voltage Protection), OPP (Over Power Protection), and SCP (Short Circuit Protection).

 

The new SuperNOVA 650 and 550 PSUs are backed by a 5-year warranty and EVGA customer support. No word on pricing or availability yet.

EVGA SuperNOVA 1200 P2 Power Supply Now Available

EVGA have just released their latest SuperNOVA series power supply, and rated at 80 Plus Platinum, their new 1200w behemoth is more than capable of powering an ultra-high end rendering workstation, mining rig (if people still do that), or just an awesome gaming system.

Thanks to it’s fully modular design, high amperage single 12V raid, Japanese Nippon Chemi-Con solid state capacitors, 140mm double ball bearing fan, as well as all the usual safety features such as over power, under power, over voltage, short circuit and over current protection, the new NOVA has just about everything you could want from a premium grade power supply.

The price is a bit steep at $269.99, but the NOVA series has proven to be a solid investment in the past, and one cannot simply ignore the fact that it comes backed up by a stunning 10-year warrant.

“Hand of God” Spotted By NASA Telescope

NASA captured some X-Ray images with the help of its Nuclear Spectroscopic Telescope Array, or NuSTAR for short. The image resulted in a hand-shaped celestial object that resembles the “Hand of God”.

“NuSTAR’s unique viewpoint, in seeing the highest-energy X-rays, is showing us well-studied objects and regions in a whole new light,” NuSTAR principal investigator Fiona Harrison, of the California Institute of Technology in Pasadena, said in a statement.

It illustrates a pulsar wind nebula, produced by the dense remnant of a star that exploded in a supernova. The remnants created afterwards a pulsar, called PSR B1509-58, or B1509 for short, which spins around 7 times per second blowing a wind of particles into material ejected during the star’s death throes. As these particles interact with nearby magnetic fields, they produce an X-ray glow in the shape of a hand. Scientists however aren’t sure whether the ejected material actually assumes the shape of a hand, or whether its interaction with the pulsar’s particles is just making it appear that way.

The red cloud appearing at the fingertips is a separate structure called RCW 89. Astronomers believe the pulsar’s wind may be heating the cloud and producing the low-energy X-ray glow.The X-ray energies seen by NuSTAR range from 7 to 25 kiloelectron volts, or keV, whereas the energies seen by Chandra range from 0.5 to 2 keV.

This could be an example of pareidolia, a phenomenon which makes people see familiar things in unusual shapes. However, despite its supernatural appearance, the “Hand of God” figure was produced by a natural astrophysical phenomena.
