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…

Enceladus – possibility for life to evolve!
Enceladus, named after a Greek mythology giant, is the sixth largest moon of the planet Saturn known for its icy surface which makes it the most reflective bodies of the Solar System. It’s not just the icy and the reflective surface that makes it eminent but the hydrothermal vents spewing water vapor and ice particles from an underground ocean beneath the icy crust of Enceladus. It has an icy, shiny, white and bright surface: The temperature is about -201 degrees C ( -300 degrees F) which makes it extremely cold. It the brightest object in the solar system as the solid ice surface reflects sunlight like freshly fallen snow.…

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…

Astronomy Q&A
So I was wondering what to different for my blog and it hit me. This one. I am going to pick 5 astronomy related questions from Quora and answer them! Serious ones and sometimes funny ones. (Maybe in the future I will take questions from the public and answer five out of them.) And it doesn’t end there. Q&A is going to happen twice in a month. One week about Astronomy and one week about Life Advices/Interesting Facts. So this week’s picked up questions: What would happen to your naked arm in the vacuum of outer space? Answer: Arms or any part of the body, you are going…

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…
