“It Sparkles” –NASA Cracks Code of Asteroid Bennu’s Particles

Bennu Asteroid

 

“Among Bennu’s many surprises, the particle ejections sparked our curiosity, and we’ve spent the last several months investigating this mystery,” said Dante Lauretta, OSIRIS-REx principal investigator at the University of Arizona about the objects active discharging of particles into space. “This is a great opportunity to expand our knowledge of how asteroids behave.”

“Stranger Than Imagined” –Weird Dynamics of Earth’s Star

 

NASA Parker Probe

 

Since it’s launch in 2018, NASA’s Parker Solar Probe has returned unprecedented data from near the Sun, culminating in new discoveries published on Dec. 4, 2019, in the journal Nature revealing that the dynamics of our star are even stranger than once imagined.

“Fate of Our Solar System” –Giant Planet Found Orbiting Dying White Dwarf Star

 

White Dwarf Planet

 

“It was one of those chance discoveries,” says astrophysicist Boris Gänsicke, from the University of Warwick , about the finding by  researchers using ESO’s Very Large Telescope of the first evidence of a giant planet associated with a white dwarf star. The planet orbits the hot white dwarf, the remnant of a Sun-like star, at close range, causing its atmosphere to be stripped away and form a disc of gas around the star. This unique system hints at what our own Solar System might look like in the distant future.

“Magic Islands” –Titan’s Very Weird Lakes

 

Lakes of Saturn's Titan

 

“The more we learn about Titan, the more we learn that we can’t ignore the lakes,” said Kendra Farnsworth, a planetary scientist at the University of Arkansas in Fayetteville and lead author of the new study that explains how bubbles erupt in frigid hydrocarbon lakes on Saturn’s largest moon Titan made up of methane and ethane, potentially creating fizz violent enough to form unusual geologic features.

“Great Oxidation Event” –A Story of Volcanoes, Tectonics and Bacteria Unique to Earth?

Great Oxidation Event

 

“Most people think the rise of oxygen was linked to cyanobacteria, and they are not wrong,” said James Eguchi, a NASA postdoctoral fellow at the University of California, Riverside who led a new study suggesting that the first burst of oxygen was added by a spate of volcanic eruptions brought about by tectonics. “The emergence of photosynthetic organisms could release oxygen. But the most important question is whether the timing of that emergence lines up with the timing of the Great Oxidation Event. As it turns out, they do not.”

Solar Sleuths Solve 60-Year-Old Mystery of Sun’s Magnetic Waves

Sun's Chromosphere

 

“This new research opens the door to providing a new understanding of the mystery surrounding the Sun’s magnetic waves. This is a crucial step towards explaining the coronal heating problem—where the temperature a few thousand kilometers from the surface—is hotter than the heat source itself,” said Dr. Ben Snow, from the University of Exeter and a co-author of a new study that led to the ground-breaking discovery of why the Sun’s magnetic waves strengthen and grow as they emerge from its surface, which could help to solve the mystery of how the corona of the Sun maintains its multi-million degree temperatures.

“Biology’s Hubble Telescope” –A Time Machine To Explore Evolution of Life

DNA IMage

 

“What we’ve made lets us dig ten times deeper than what we’ve been able to do before, helping us to see hundreds of millions of years into the past,” says Evan Floden, a researcher at the Center for Genomic Regulation in Barcelona who led on developing a new tool that simultaneously compares 1.4 million genetic sequences. “Our technology is essentially a time machine that tells us how ancient constraints influenced genes in a way that resulted in life as we know today, much like how the Hubble Space Telescope observes things that happened millions of years ago to help us understand the Universe we live in today.”
