Sound barrier was broken a long time ago. Ever since that law was broken, sci-fi geeks have been waiting to see more of “fantasy come true”. One of which is the warp drive from star trek. How far are we from that? Or how close are we? Let me not drag the answer, scientists believe that it is quite impossible considering Einstein’s Theory of Relativity. Nothing can travel faster than the speed of light – however, if we could compact and expand the fabric of space-time ahead of and behind us, technically we could travel faster than the speed of light. Technically. Anyway, like i mentioned earlier It’s just…

New discoveries – yet again! 72 new galaxies found.
Astronomers at the ESO (European Southern Observatory) have found 72 new galaxies hiding in the plain sight. This was observed by Multi Unit Spectroscopic Explorer (MUSE), a second generation instrument in development for the Very Large Telescope (VLT) of the ESO. The galaxies were observed on the area in space called “Hubble Ultra Deep Field”, usually where many telescopes are pointed in search for such galaxies. But what makes MUSE different is that, it uses spectroscopy to break light into its component colors. And as it happens, these galaxies emits Lyman-alpha light which is a particular wavelength of ultraviolet light – which MUSE was able to detect unlike other telescope…

Answers ready to be served! – Astronomy Q&A for the month.
As mentioned in my last month’s post, I am dedicating a week to answer questions picked from Quora about Astronomy. So here is this month’s batch. What would happen if a bullet was shot in outer space? Answer: Space does not have oxygen but that doesn’t mean your gun won’t fire. Modern gun has ammunition that has its own oxidizer that triggers the explosion. So when you shoot a gun into space two things happen: Experience Newton’s third law of motion, you being on the other side and with higher mass, you will move backwards. The bullet keeps going into the space towards infinity as universe expands faster than a…

Have we been visited by Aliens already?
We all have wondered at least once in our lifetime, whether we have been visited by green little people – but never have actually have had evidence around it. So let me sum up certain theories that has been around. That will give you something to think about. Going back to the 40s and 50s stories, there have been reports of “flying saucers” modernly came to known as the UFOs (Unidentified Flying Objects) became American cultural phenomena. It goes on until today. Although there hasn’t been any evidence or claims from the governments that they are UFOs, the sightings of these “alien spacecrafts” haven’t stopped. Thats where…

We are made of stardust. But not just from this Galaxy!
Yes, we could be space travelers. A study proved that Humans are made of stardust. A theory, which used to go like this – Humans and the galaxies in the universe share 97% of atoms that is responsible and vital for life. Now, the theory is no longer just a theory – it has been proved. The fundamental elements for life on Earth – called the building blocks are Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus and Sulfur. These six elements are the basic requirements for life anywhere. And a while back, scientists had proved it by measuring the wavelengths of light – using spectroscopy – from the stars located at the…
