Scientists say solar system affects Earth’s carbon cycle

Scientists say solar system affects Earth’s carbon cycle

Science
Feb. 11 (UPI) -- Scientists have discovered evidence that Earth's carbon cycle and global climate is influenced by periodic changes in the shape of Earth's path around the sun. According to a new study, published this week in the journal PNAS, scientists found the evidence hiding in ancient layers of mudstone. Chemical analysis of the ancient mudstone revealed links between past orbital changes and two major extinction events, the Triassic-Jurassic mass extinction event, around 201 million years ago, and the Toarcian extinction event, or Toarcian turnover, around 183 million years ago. "Our work shows that for the 18 million years or so in between the Triassic-Jurassic mass extinction and the Toarcian oceanic anoxic event, Earth's global carbon cycle was in a constant state of change," M...

NASA, Europe space agency launch Solar Orbiter mission

Science
ORLANDO, Fla., Feb. 9 (UPI) -- One of the most advanced science missions to study the sun in history -- the Solar Orbiter -- launched aboard an Atlas V rocket from Florida on Sunday night. The rocket lifted off into a partly cloudy sky with a full moon as planned at 11:03 p.m. EST from Space Launch Complex 41 at Cape Canaveral Air Force Station, adjacent to Kennedy Space Center. The Solar Orbiter satellite will aim multiple cameras and sensory equipment at the sun's polar regions, images of which have never been taken. It's part of a concerted effort by NASA and the European Space Agency to better understand solar radiation and solar flares. "The mission will be able to look at the poles of the sun, which will be the first time ever that we will be able to look at the poles," said Cesar ...

ORLANDO, Fla., Feb. 8 (UPI) -- One of the most advanced science missions to study the sun in history -- the Solar Orbiter -- is scheduled for launch on Sunday night in Florida. The launch is planned for 11:03 p.m. EST at Space Launch Complex 41 at Cape Canaveral Air Force Station, which is adjacent to Kennedy Space Center. A two-hour launch window exists in case of delays. The satellite will aim multiple cameras and sensory equipment at the sun's polar regions, images of which have never been taken. It's part of a concerted effort by NASA and the European Space Agency to better understand solar radiation and solar flares. "The mission will be able to look at the poles of the sun, which will be the first time ever that we will be able to look at the poles," said Cesar Garcia, Solar Orbite...
Scientists pinpoint release of energy that powered series of solar flares

Scientists pinpoint release of energy that powered series of solar flares

Science
Jan. 17 (UPI) -- Scientists have precisely pinpointed the explosive release of energy that powered a series of solar flares -- a first. The solar flares were originally recorded in 2017 by the Expanded Owens Valley Solar Array, EOVSA, a radio telescope operated by the New Jersey Institute of Technology. While studying solar activity, the radio telescope spotted the birth of a new region of magnetic energy adjacent to an existing sunspot. The explosion of energy sent extremely hot plasma spewing from the solar atmosphere out into space. Recently, scientists reexamined the data collected by the EOVSA, looking for unique patterns recorded in microwave spectrum. Until now, scientists have only been able to study solar flares by examining the electromagnetic signatures registered at the phot...
