For centuries, comets have captured our imagination. Across history they have been the harbingers of doom, inspired artists and fascinated astronomers. These icy remnants of the formation of the Solar System hold secrets to help us understand the events nearly 5 billion years ago. But before these secrets can be revealed, comets have to be studied and to study them they need to be found. A team of researchers have developed a technique to hunt down comets based upon data from meteor showers and to assess if they pose any threat to us here on Earth!

The universe’s largest water reservoir, 140 trillion times the water in Earth's oceans, found near a supermassive black hole: Astronomers have discovered an enormous reservoir of water vapor near the quasar APM 08279+5255, located over 12 billion light-years away. This cosmic water supply contains 140 trillion times the water found in Earth’s oceans and surrounds a supermassive black hole 20 billion times the mass of our Sun. The quasar, which radiates energy equivalent to a thousand trillion suns, offers a glimpse into the conditions of the early universe. The discovery highlights the presence of water vapor billions of years ago, suggesting that life’s building blocks have existed for much of the universe’s history. The region around the quasar is far denser and warmer than typical galactic environments, providing key insights into how galaxies, black holes, and stars formed and evolved. This breakthrough was achieved using advanced telescopes in Hawaii, California, and France, offering an extraordinary window into the cosmos’ earliest chapters.

How Big is the Universe? According to astronomers, the Universe is about 93 billion light years in diameter. However, this estimation is just based on our current understanding of physics. This implies that the Universe could be much bigger than that. Scientists suggest that the Universe is made up of about 2 trillion galaxies. Each galaxies are of different sizes. But lets stick to our own Milky Way galaxy. The Milky Way has about 400 billion stars within it and it takes lig…
This planet known as “GJ 1214B” is made of pure water, and consists of no rocky surface. It’s nicknamed the ocean planet, as it’s completely underwater. This planet lies approximately 40 light years away and has a radius of about 10,000 miles. Credits: NASA, ESA, ESO, Artistic Illustration by Science Photo Library
This is a reflecting nebula located in the constellation Eridanus, close to Orion, also known as IC 2118 or NGC 1909. It is about 1,000 light years away from Earth
