"Youngest in the Milky Way" --Three New Planets Observed Around Infant Star

 

Eso1818a (1)

 

Although thousands of exoplanets have been discovered in the last two decades, detecting protoplanets remains at the cutting edge of science and there have been no unambiguous detections before now. The techniques currently used for finding exoplanets in fully formed planetary systems — such as measuring the wobble of a star or the dimming of starlight due to a transiting planet — do not lend themselves to detecting protoplanets.

Violent Solar Winds Create Exospheres of Shattered Rock Around the Moon & Mercury


832_24746_802303

The planets and moons of our solar system are continuously being bombarded by particles hurled away from the sun. On Earth this has hardly any effect, apart from the fascinating northern lights, because the dense atmosphere and the magnetic field of the Earth protect us from these solar wind particles. But on the Moon or on Mercury things are different: There, the uppermost layer of rock is gradually eroded by the impact of sun particles.

Wormhole Echoes Would Be One of the Greatest Discoveries Ever --"Irrefutable Proof That Black Holes Don't Exist"

"Wormholes do not have an event horizon, but act as a space-time shortcut that can be traversed, a kind of very long throat that takes us to another universe," says Pablo Bueno from KU Leuven University (Belgium). "The confirmation of echoes in the LIGO or Virgo signals would be a practically irrefutable proof that astrophysical black holes don't exist. Time will tell if these echoes exist or not. If the result were positive, it would be one of the greatest discoveries in the history of physics."

"Earthly Aliens, Unlike Anything Seen Before" --Strange, Giant Viruses Create Their Own Genes

In 2013, the discovery of two giant viruses unlike anything seen before blurred the line between the viral and cellular world. Pandoraviruses are as big as bacteria, and contain genomes that are more complex than those found in some eukaryotic organisms (whose cells contain nuclei, unlike the two other kingdoms of living organisms, bacteria and archaea). Their strange amphora shape and enormous, atypical genome led scientists to wonder where they came from.

Violent, Starburst Galaxies Form New, Massive Stars 100 Times More than Milky Way  

 

  Eso1817a

 

Astronomers using ALMA and the VLT have discovered that both starburst galaxies in the early Universe and a star-forming region in a nearby galaxy contain a much higher proportion of massive stars than is found in more peaceful galaxies. These findings challenge current ideas about how galaxies evolved, changing our understanding of cosmic star-formation history and the build up of chemical elements.

"Planetary Killer" --First Observation Ever of DNA Process that Evolves Into Drug-Resistant Bacteria

Scientists have made the first direct observation of a key step in the process that bacteria use to rapidly evolve new traits, including antibiotic resistance. Researchers recorded the first images of bacterial appendages -- over 10,000 times thinner than human hair -- as they stretched out to catch DNA. These DNA fragments can then be incorporated into bacteria's own genome through a process called DNA uptake or "horizontal gene transfer."

Today's Top Science Post: The Quantum Big Bang --"Our Universe Does Not Exist Until It's Observed"

 


P035n398

 

 

The question is no longer whether quantum theory is correct, but what it means: for almost a century, physicists have wondered whether the most counterintuitive predictions of quantum mechanics (QM) could actually be true. Only in recent years has the technology necessary for answering this question become accessible, enabling a string of experimental results—including startling ones reported in 2007 and 2010, and culminating now with a remarkable test reported in May—that show that key predictions of QM are indeed correct.

Today's "Planet Earth Report" --One of Earth’s Oldest and Strangest Trees are Dying Mysteriously

 
Adansonia_grandidieri04

 

"Some of these trees are more than 2000 years old, the team reports today in Nature Plants. But in 2011 the oldest known specimen—a shrine for rainmakers named Panke that sprouted about 2450 years ago—died and toppled over. And now seven more of the 13 oldest trees, and five of the six biggest trees, have also died, the researchers report."

"Puzzle Solved" --Mysterious Source of Microwave Light Across the Milky Way

"Though we know that some type of particle is responsible for this microwave light, its precise source has been a puzzle since it was first detected nearly 20 years ago," said Jane Greaves, an astronomer at Cardiff University in Wales and lead author on a paper announcing this result in Nature Astronomy.
