Among the amazing diversity of stars around the Sun, some very strange objects have been recently discovered…
It has been speculated that silicate particles (a component of glass) in the atmosphere of HD 189733b, located 63 light years away, gives the planet its blue color as well as a possible superheated glass storm.
Have you noticed how the full moon looks bigger on the horizon than high overhead? Actually, the two images are exactly the same size — so why do we perceive them differently? Scientists aren’t sure, but there are plenty of intriguing theories. Andrew Vanden Heuvel unravels the details of focus, distance and proportion that contribute to this mystifying optical illusion.
This is just a basic display of the abundance of elements in the known universe, the Earth, the Earth’s crust, the ocean, the atmosphere, and the human body.
One of the most significant scientific discoveries of the early 21st century is surely the Higgs boson, but the boson and the Higgs Field that allows for that magic particle are extremely difficult to grasp. Don Lincoln outlines an analogy (originally conceived by David Miller) that all of us can appreciate, starring a large dinner party, a raucous group of physicists, and Peter Higgs himself.
Why can’t Astronomers actually say at what point in the sky the big bang took place?
