Congrats Dr. Happer.

I’ve been waiting to find out who will be Pres. Trump’s science adviser. It appears to be physicist Dr. William Happer, a physicist currently teaching at Princeont University, and former Director of the U.S. Department of Energy’s Office of Science from 1991–1993. He’s no slouch as a scientist. His work for the Air Force on the sodium guidestar laser platform for the military’s missile defense program provided information on the tropopause layer in the upper atmosphere, which is where atmospheric wave fronts distort both starlight and laser emissions, and where heat either begins to leak into space or does not, depending on how much and what kind of gas is blocking heat radiation.

The tropopause is the boundary between the troposphere, where we live and where weather takes place, and the stratosphere. The layers above that are the stratosphere, where stratocirrus clouds form as floating clouds of ice, the mesosphere, the thermosphere and the top, very thin layer, the exosphere. Beyond that is space.

It was a great moment for physicists and scientists around the world in 2016 when one of the greatest ever scientific discoveries was announced. Although technically the first gravitational waves were detected in 2015, it wasn’t until further detections were made in 2016 that scientists finally conceded they did exist and that Albert Einstein’s theory of relativity could finally be proved. Following on from that, scientists also discovered that as well as a great detector LIGO is the best producer of gravitational waves.

Interestingly, Seager, who studies bio signatures in exoplanet atmospheres, has suggested that two inhabited planets could reasonably turn up during the next decade, based on her modified version of the Drake equation, Space.com notes. Her equation focuses on the search for planets with biosignature gases — gases produced by life that can accumulate in a planet atmosphere to levels that can be detected with remote space telescopes.

Harnessing the extra light — new method.

TORONTO, ON (Canada) – University of Toronto (U of T) researchers have demonstrated a way to increase the resolution of microscopes and telescopes beyond long-accepted limitations by tapping into previously neglected properties of light. The method allows observers to distinguish very small or distant objects that are so close together they normally meld into a single blur.

Telescopes and microscopes are great for observing lone subjects. Scientists can precisely detect and measure a single distant star. The longer they observe, the more refined their data becomes.

The Universe as we know it is made up of a continuum of space and time — a space-time fabric that’s curved by massive objects such as stars and black holes, and which dictates the movement of matter.

Thanks to Einstein’s gravitational waves, we know disturbances can propagate through both space and time. But what’s less understood is exactly how that happens when properties of the fabric is continuously shifting.

Feb. 3 (UPI) — A new image from the Hubble Space Telescope displays the beauty of a stellar death — in this case, the death of a low-mass star, similar to our sun in size.

Once a red giant, the star is currently in a transitionary phase: It’s on its way to becoming a planetary nebula. The Hubble image reveals the star’s layers of gas and dust being shed and thrown outward. The expelled material, now forming clouds, could eventually form new stars and planets.

Astronomers rarely catch dying red giants in their transitionary phase. It will only be a few thousand years before the star is a pure planetary nebula — a blip in space time.

Theoretical physicists and astrophysicists, investigating irregularities in the cosmic microwave background (the ‘afterglow’ of the Big Bang), have found that there is substantial evidence of our universe being a vast and complex hologram. A UK, Canadian and Italian study has provided what researchers believe is the first observational evidence supporting a holographic explanation of the universe. The researchers from the University of Southampton (UK), University of Waterloo (Canada), Perimeter Institute (Canada), INFN, Lecce (Italy) and the University of Salento (Italy) have published their findings in the journal Physical Review Letters.
