This image, released for Hubble’s 17th anniversary, shows a region of star birth and death in the Carina Nebula. The nebula contains at least a dozen brilliant stars that are 50 to 100 times the mass of our Sun.
The large Whirlpool Galaxy (left) is known for its sharply defined spiral arms. Their prominence could be the result of the Whirlpool’s gravitational tug-of-war with its smaller companion galaxy (right).
End of this week holds in store a nice and a rare spectacle – a total eclipse of the Sun. On this day, the Moon swings in front of the Sun casting a shadow onto the surface of the Earth. Those of us in the path of this shadow will be lucky to see the Sun partially or fully covered: the solar eclipse.
Last night Earth experienced a geomagnetic storm and aurora were visible in the Northern U.S. states. These images of aurora were captured on March 17, 2015, around 5:30 a.m. EDT in Donnelly Creek, Alaska by Sebastian Saarloos. These aurora might have been caused by the fast solar wind streaming from¬†two solar coronal holes. Image Courtesy of Sebastian Saarloos.
