The Interstellar Travel

Black holes have always been an interesting subject of conversation among the space enthusiastic. And if you have been following this blog from the very beginning, you will know that I’ve already written four blogs just about black holes and researches related to black holes. So this is yet another blog about black holes because-there aren’t just enough! So this blog is about how the latest research on black hole proved Einstein’s general theory of relativity! For the first time, astronomers have confirmed Einstein’s century old theory by observing action near black hole.   Using the European Southern Observatory’s Very Large Telescope (VLT) in Chile, an international team of professional sky-gazers watched as a star swung by the super massive black hole at the center of the Milky Way Galaxy, and observed the effect the black hole’s extreme gravitational field had on the star’s motion.   By accurately tracing the position and speed of this single star, known as S2...

All the brilliant minds have the habit of going with a bang. This is exactly what Prof. Stephen Hawking did when he passed away on March 14, 2018. The physicists died at the age of 76 and it seemed like the world stood still. Tributes flooded in for the greatest scientist of all time. Everybody was celebrating his work and achievements. But this wasn’t the end. The physicist left behind some more ground breaking theories in his residence at Cambridge that won him countless honors in the field of cosmology, general relativity, quantum gravity and black holes . However, one of his papers is yet to be published which will prove his greatest contribution in the field of Multi-verse.   According to reports, colleagues of Hawking have revealed the renowned theoretical physicist’s final academic work involved the theory explaining how humans could detect parallel universes .  In the paper, Hawking has given some ground breaking mathematics needed to find...

New Horizons Spacecraft out of Hibernation mode Speeding through the outer space of our Solar system, New Horizons spacecraft has awakened after its five and half months of hibernation, ready for its second act after its 2015 flyby of Pluto. This spacecraft is 3.8 billion light years away from Earth and has been sending photographs and information about our beloved planet, Pluto. New horizons woke up with the on-board timer late Monday, but the radio signals confirms that it took six hours to reach the   Earth that the New horizon has emerged, hence completing journey   at light speed   at 2.12am   EDT, Tuesday. Alice Bowman, the New Horizons operation manager confirmed that the spacecraft has been functioning normally and efficiently. Back in 2015, the spacecraft had sent stunning images of the Pluto surface like vast mountain ranges, cryovolcanoes, glaciers, methane snow and other surprising geographic activity. New Horizons is now on a n...

As mysterious as it can get, Universe has always been a place for strange and weird things. Now, scientists have a “Super-Void” in space which is missing galaxies! So before we get in to the topic, first let’s discuss what is “Void” According to Wikipedia, Voids or Cosmic Voids , as they are called, are vast spaces between galaxy filaments in the universe, which has few or 0 galaxies. Galaxy filaments are largest know structures in the universe, which have thread-like structures. They form boundaries between voids in space. These voids have very less density of matter that is considered for typical observable universe. Voids are believed to be formed in Big Bang, followed by massive collapse its mass and compressed by Baryonic matter . After Big Bang, there were lots of areas with high and low densities, which were changing rapidly. The regions with high density collapsed rapidly under gravity eventually causing foam-like structure of cosmic web of voids. Voids loc...

The very idea of black hole is baffling and scary at the same time. Many scientists have dedicated their lives for studying these scary things. Why scary? C’mon let’s be honest.   Getting sucked by a black hole due to its strong gravitational field means instant death. Although we still don’t know what exactly will happen if a human being falls in the black hole , we have drawn our conclusions based on what it does to light. That’s why; it may sound even scarier when we learned that scientists have discovered a dozen of black holes teaming up at the center of our galaxy-Milky way.   Data from NASA’s orbiting Chandra X-ray observatory has allowed researchers to detect a group of black holes surrounding Sagittarius A*. Sagittarius A* is a super massive black hole at the center of Milky Way-that’s where we are. For a while now, scientists have believed that there is something at this place and now it’s confirmed! Based on the findings,   up to 10,000 black h...
