Here and gone: Outbound comets are likely of alien origin

IMAGE: Researchers calculated the typical paths of long-orbit comets (blue) perturbed by a passing gas-giant-sized object (white) and objects of interstellar origin (red). view more  Credit: NAOJ Astronomers at the National Astronomical Observatory of Japan (NAOJ) have analyzed the paths of two objects heading out of the Solar System forever and determined that they also most likely originated from outside of the Solar System. These results…

The core of massive dying galaxies already formed 1.5 billion years...

IMAGE: The red galaxy at the center is a dying galaxy at 12 billion years ago. Astronomers measured the motion of stars in the galaxy and found that the core... view more  Credit: NAOJ/M. Tanaka Astrophysics, Galaxies: The most distant dying galaxy discovered so far, more massive than our Milky Way -- with more than a trillion stars -- has revealed that the 'cores' of these…

NJIT scientists measure the evolving energy of a solar flare’s explosive...

Toward the end of 2017, a massive new region of magnetic field erupted on the Sun's surface next to an existing sunspot. The powerful collision of magnetic energy produced a series of potent solar flares, causing turbulent space weather conditions at Earth. These were the first flares to be captured, in their moment-by-moment progression, by NJIT's then recently opened Expanded Owens Valley Solar Array (EOVSA)…

VHF radar operation starts in Thailand for observation of plasma bubble

Taking the temperature of dark matter

Warm, cold, just right? Physicists at the University of California, Davis are taking the temperature of dark matter, the mysterious substance that makes up about a quarter of our universe. We have very little idea of what dark matter is and physicists have yet to detect a dark matter particle. But we do know that the gravity of clumps of dark matter can distort light…

NASA infrared data analyzes cloud top temperatures in Tropical Cyclone Claudia

IMAGE: On Jan. 14 at 1:23 EST (0623 UTC) NASA's Aqua satellite analyzed Tropical Storm Claudia using the Atmospheric Infrared Sounder or AIRS instrument. AIRS found coldest cloud top temperatures as... view more  Credit: Credit: NASA JPL/Heidar Thrastarson Satellite data of Tropical Cyclone Claudia's cloud top temperatures revealed that the storm was weakening. One of the ways NASA researches tropical cyclones is using infrared data that…

Astronomers reveal interstellar thread of one of life’s building blocks

IMAGE: This infographic shows the key results from a study that has revealed the interstellar thread of phosphorus, one of life's building blocks. Thanks to ALMA, astronomers could pinpoint where phosphorus-bearing... view more  Credit: ALMA (ESO/NAOJ/NRAO), Rivilla et al.; ESO/L. Calçada; ESA/Rosetta/NAVCAM; Mario Weigand, www.SkyTrip.de Phosphorus, present in our DNA and cell membranes, is an essential element for life as we know it. But how it…

NASA, NOAA analyses reveal 2019 second warmest year on record

IMAGE: This plot shows yearly temperature anomalies from 1880 to 2019, with respect to the 1951-1980 mean, as recorded by NASA, NOAA, the Berkeley Earth research group, the Met Office Hadley... view more  Credit: NASA GISS/Gavin Schmidt According to independent analyses by NASA and the National Oceanic and Atmospheric Administration (NOAA), Earth's global surface temperatures in 2019 were the second warmest since modern recordkeeping began in…

Dating a galaxy crash

Mackereth The dwarf galaxy Gaia-Enceladus collided with the Milky Way probably approximately 11.5 billion years ago. A team of researchers including scientists from the Max Planck Institute for Solar System…

Active asteroid unveils fireball identity

IMAGE: These are images capturing the 2017 fireball from different angles and a map showing where the cameras were located. view more  Credit: NAOJ/Kasuga et al. At around 1 a.m. local standard time on April 29, 2017, a fireball flew over Kyoto, Japan. Compared to other fireballs spotted from Earth, it was relatively bright and slow. Now, scientists have determined not only what the fireball was,…
