• New Supernova Spotted in M82 (or Cigar) Galaxy

    Today morning, a supernova was spotted in the starburst galaxy of M82 (also known as Cigar Galaxy). It is known as a starburst galaxy due to the high rate of star formation.

Gigantic Space Weather Explosions in Venus

Recently, researchers have found a weird space weather phenomenon called "Hot flow anomalies", which happens in the outskirts of Earth in the magnetosphere. The same phenomenon happens in Venus, except in gigantic proportions. It is so huge that its actually bigger than the size of the planet and it happen multiple times a day.

Earth has a magnetic field which protects us from these kind of weather phenomenons. However, Venus doesn't have the magnetic shield. Hence, the hot flow anomalies happen right on top of the planet. Venus has an outer layer called Ionospere. A pressure balance between the ionosphere and hot flow anomalies create planet-scale disruptions, thus, sucking up the ionosphere away from the surface of the planet (which is shown in the image above).

New Supernova Spotted in M82 (or Cigar) Galaxy


Today morning, a supernova was spotted in the starburst galaxy of M82 (also known as Cigar Galaxy). It is known as a starburst galaxy due to the high rate of star formation. The M82 galaxy is located about 11.4 million light years away in the constellation of Ursa Major. It's classified as a Type 1a supernova (SN1a) or a white dwarf supernova. It happens to an old star when they run out of fuel and thus, eventually they end up as a white dwarf. The supernova hasn't appeared to have reached its peak brightness yet and it's expected to reveal more information with close observation over the next few days.

The Necklace Nebula (Picture of the Day)


The Necklace nebula (also called PN G054.2-03.4) is a planetary nebula which is about 15,000 light years away in the constellation of Sagitta. It spans approximately 2 light years across. The nebula got its name due to the dense gas and dust which resembles a necklace. The nebula is caused by a pair of stars orbiting very close together. The two stars are revolving around each other so fast that it completes one orbit in roughly 1 day.

Pioneer 10: First Spacecraft to Leave the Solar System (Fact of the Day)


Pioneer 10 is an American spacecraft launched on March 3, 1972. The main goal of the spacecraft was to flyby Jupiter and eventually fly out of the solar system. The spacecraft has many accomplishments to its name and some of them are as follows. It is the first spacecraft to fly beyond Mars' orbit, through the Asteroid Belt, flyby Jupiter and eventually flying past the furthest planet at that time, Neptune, on 13th June 1983. Thus, it became the first spacecraft to leave the Solar System. On January 23 2003, all the connections were lost with the spacecraft when it was 12 billion km (80 AU) from Earth. In the current speed of 12.51 km/s or 28,000 miles/hr (which is approx. 0.000041 the speed of light), the spacecraft would pass the nearest star in its trajectory, Aldebaran, in about 2 million years.

NGC 5866: The Spindle Galaxy (Picture of the Day)


The Spindle Galaxy (or NGC 5866) is a lenticular galaxy which lies about 44 million light years in the constellation of Draco. It's approximately 60,000 light years across. One of the unique features of this galaxy is the extended dust disk which is unusual for a lenticular galaxy. The dust disk is generally found near the nucleus in a lenticular galaxy. The mass of the galaxy is very similar to our galaxy while the diameter of the galaxy is smaller than our Milky Way Galaxy.
