Even though light travels extremely fast (300,000,000 meters per second), objects in space are so far away that it takes a significant amount of time for light from those objects to reach us. So if you look through a telescope at a distant object, you are seeing that object at some time in the past - seeing back in time.

Your Brain Makes Its Own Version Of Valium
Valium, the anti-anxiety drug that was once the most popular prescription medication in America, might have a naturally occurring relative in the mammalian brain, according to a new paper in Neuron.
Stanford University researchers have discovered that a protein called diazepam binding inhibitor (DBI) can have some of the same effects as Valium.Diazepam (Valium), belongs to a class of psychoactive drugs known as benzodiazepines, and can be used to stop epileptic seizures, especially during clusters of repeated seizures.
"Our results show for the first time that a nucleus deep in the middle of the brain generates a small protein product, or peptide, that acts just like benzodiazepines," senior author John Huguenard explained in a press statement.
DPI is also known as ACBP, and it's an intracellular transport protein that exists in every cell in the body. Researchers have found that in a certain part of the brain (the thalamic reticular nucleus), DPI becomes an anti-epileptic compound. It binds to the same nerve receptors in the brain as benzodiazepines, enhancing the inhibiting effect of a neurotransmitter called GABA.
The calming protein, which seems to only be generated in this region in the middle of the brain, could be key in developing anti-seizure treatments. The researchers suggest it could be used in anxiety and sleep disorders as well.

We live in a world of choices, where we have to make decisions every day. They all have somehow an impact on our lives. But have you ever thought how affected are your everyday choices?
Well, imagine that all piles of your material property would be given to an anthropologist. Would it be possible to put together an accurate portrait of your personality? Would it describe something exceptional or rather something typical?
Sometimes we should judge the amount of the free-willed choices we make. Are they really a result of our own self-determination?
Question. Analyze. Think. - KTS.
all this space and no aliens?
"If we consider that life on Earth took just several hundred million years to evolve, and the universe has existed for at least 14 billion years, then it is likely that other planets have had a much longer time to support life than us. With every star now thought to host at least one planet there are billions of potential planets out there and it's highly unlikely that not one of these grew life like Earth has done." (Jonathan O'Callaghan)

The Crab Nebula is a supernova remnant in the constellation of Taurus.
It was first identified in 1731 by John Bevis, and independently rediscovered in 1758 by Charles Messier.
The nebula was the first astronomical object identified with a historical supernova explosion.

Pillars of Creation are clouds of interstellar gas and dust in the Eagle Nebula, about 7,000 light years from Earth. The name comes from its large region of star formation. The gas and dust are in the process of creating new stars, while also being eroded by the light from nearby stars that have recently formed.
