Black Holes In Pics: Some fun facts about them from NASA
1/5 Did you know there are two kinds of black holes? Yes, you read that right! According to NASA, black holes can be differentiated into two depending on their mass. The first is a Stellar Black Hole which is formed from a single star. It can be three times the size of our Sun. The other is a Supermassive Black Hole which forms due to merging of other black holes. It is a massive black hole which resides in the center of galaxies and is capable of engulfing other stars.

2/5 How many black holes are there? Well, according to NASA, there are hundreds of black holes in space. However, scientists assume that black holes are present in thousands. (NASA)

3/5 Any matter that is consumed by black holes is eventually crushed into one single point, which is called Singularity. According to NASA, a singularity, located at the center of the black hole, is vanishingly small, yet has an infinite density. (NASA)

4/5 Is there a supermassive black hole in our galaxy? Yes, there is! Located nearly 26,000 light years away at the center of our Milky Way Galaxy is Sagittarius A*, the supermassive black hole which could potentially one day swallow the whole Milky Way Galaxy. (NASA)
5/5 Can our Sun become a black hole? The answer is no. According to NASA, a black hole forms from a star that is nearly 15 to 20 times the size of our Sun. So, you need not worry about being swallowed by our own Sun. So, when our Sun eventually runs out of fuel, it will become a white dwarf and expand in size, turning into a red giant. (Pixabay)

Solar storms can pose a great threat to Earth! The horrific Carrington Event in 1859 is one of the biggest examples of what Solar storms are capable of doing. From power, and satellites to radio communication, everything can be in danger. However, there is always a bright side too, and in this case, it is the fascinating light show at the poles. And NASA is making sure to deliver every possible view from space. This time, the space agency shared the latest images taken from the International Space Station of the southern lights or Aurora Australis above the Indian Ocean near Antarctica. Bob Hines, a pilot currently on the ISS, managed to take the picture of auroras seen on Earth.

This comes a few weeks after the images taken by the James Webb Space Telescope of Jupiter and last month's stunning shots of the Carina Nebula and Southern Ring Nebula. In the image posted by NASA on its Instagram page shows the vibrant displays of light around Earth's North and South Poles that are caused by the interaction of solar particles spewed by the Sun and our planet's protective magnetic field that helps to give birth to these dancing lights. Mostly, these interactions are relatively limited and go unnoticed by us on Earth.

NASA says that once the solar particles are in the atmosphere, these energized particles collide with atmospheric gases to shoot off these auroras. How do those red and green hues emerge? Simply because of the collision of solar particles particularly with atmospheric oxygen. While blue and purple hues are the result of the interaction of solar particles with nitrogen in our atmosphere.

Do auroras only appear on Earth?

This may be surprising to many, but Earth isn't the only planet to have auroras! NASA explained that if a planet has an atmosphere and magnetic field, they likely have auroras. This was the case with our solar system neighbour Jupiter, which showed off its beautiful auroras recently.
