Real-time map of aurora borealis

mindblowingscience:

Hey guys, I just found out that the NOAA space weather prediction centre has a real time map of the aurora’s that are going on right now due to the X-class solar flare from the sun.

It shows the areas that the aurora is visible from and is updated every 30 seconds.

There is also a map for the south pole.

Enjoy!

WOW! I didn’t have a clue about this resource. Kudos to Tynan Plillips for the find.

Just how big is the Sun?

The Sun is large enough that approximately 1.3 million Earths could fit inside, if squashed in. If the Earths retain their spherical shape, 960,000 Earths would fit.
But can you visualize that number of Earths?
Click on the picture above to see what 1.3 million Earths look like.

Seeing a supernovae within hours of the explosion
For the first time ever, scientists have gathered direct evidence of a rare Wolf-Rayet star being linked to a specific type of stellar explosion known as a Type IIb supernova. Peter Nugent of the Lawrence Berkeley National Laboratory says they caught this star – a whopping 360 million light years away – just a few hours after it exploded.

WOW! This is a great discovery.

Our cosmic address gets an update.

Astronomers have discovered that our galaxy belongs to a massive cluster of 100,000 galaxies, which they’ve called Laniakea. Time to replace all your stationery, because our new address is: the Earth, the Solar System, the Milky Way, Laniakea, the Universe: http://bit.ly/1prGDsD

The Beautiful Rings of Saturn

The Saturn system reveals tantalizing vistas. NASA’s robotic spacecraft named Cassini carries with it 12 instruments designed to take precise measurements of Saturn and its surroundings, including Titan, other icy moons, and the rings, as well as the magnetic environment.
For many of us, however, the images are what put us there, at Saturn, almost a billion miles away from home. Some of those images unveil overwhelming beauty. Others show tricks of light and seemingly magical oddities. Some reveal events from the distant past that have been preserved for eons, while other views depict processes that are changing now, like live news.

This is just unreal.

European Space Agency's Rosetta probe arrives at distant comet

ESA’s Rosetta team create history. So much could have gone wrong in those 10 long years. If the rest of mission goes as planned then it will become the first spacecraft to orbit a comet on its journey around the sun, and in November 2014 mission controllers will look to place the Philae robotic lander on the surface of the comet, another first. 

Today’s milestone is just the beginning in many ways. 

How Does the Sun Appear on Other Planets?

To avoid any confusion, the little spaceship seen in each frame is irrelevant to the message. I believe the original designer put them there to help establish how much light the sun generates on each planet. (Each comparison was based on the approximate apparent visual magnitude of the sun for each planet)

We are stardust, made of the stuff of dying suns. NASA simulates our basic building blocks. Scientists at NASA’s Ames Research Center in California have developed a way of recreating the dust and gas found around dying red giant stars that eventually become planet-forming interstellar dust.: http://www.gizmag.com/interstellar-dust-planet-formation-nasa/31957/

This is such a fascinating research project. Who knew we could gleam such fascinating insights from humble dust grains?
