Cosmic collision lights up the darkness

IMAGE: This image, taken with the Wide Field Camera 3 (WFC3) and the Advanced Camera for Surveys (ACS), both installed on the NASA/ESA Hubble Space Telescope, shows the peculiar galaxy NGC... view more  Credit: ESA/Hubble, NASA Though it resembles a peaceful rose swirling in the darkness of the cosmos, NGC 3256 is actually the site of a violent clash. This distorted galaxy is the relic of…

A star disturbed the comets of the solar system in...

About 70,000 years ago, when the human species was already on Earth, a small reddish star approached our solar system and gravitationally disturbed comets and asteroids. Astronomers from the Complutense University of Madrid and the University of Cambridge have verified that the movement of some of these objects is still marked by that stellar encounter. At a time when modern humans were beginning to leave…

NASA finds depression strengthening into Tropical Storm Emilia

IMAGE: The GPM core observatory satellite passed over Tropical Depression Six-E on June 28 at 1:30 a.m. EDT (0530 UTC) as it was strengthening into a tropical storm. Powerful storms circling... view more  Credit: Credits: NASA/JAXA/NRL The Global Precipitation Measurement mission or GPM core satellite passed over Tropical Depression Six-E in the Eastern Pacific Ocean and found heavy rainfall occurring in two areas. Shortly after GPM…

NASA balloon mission captures electric blue clouds

On the cusp of our atmosphere live a thin group of seasonal electric blue clouds. Forming 50 miles above the poles in summer, these clouds are known as noctilucent clouds or polar mesospheric clouds -- PMCs. A recent NASA long-duration balloon mission observed these clouds over the course of five days at their home in the mesosphere. The resulting photos, which scientists have just begun…

First interstellar immigrant discovered in the solar system

IMAGE: These are images of 2015 BZ509 obtained at the Large Binocular Telescope Observatory (LBTO) that established its retrograde co-orbital nature. The bright stars and the asteroid (circled in yellow) appear... view more  Credit: C. Veillet / Large Binocular Telescope Observatory A new study has discovered the first known permanent immigrant to our Solar System. The asteroid, currently nestling in Jupiter's orbit, is the first known…

JHU performs first laboratory simulation of exoplanet atmospheric chemistry

Scientists have conducted the first lab experiments on haze formation in simulated exoplanet atmospheres, an important step for understanding upcoming observations of planets outside the solar system with the James Webb Space Telescope. The simulations are necessary to establish models of the atmospheres of far-distant worlds, models that can be used to look for signs of life outside the solar system. Results of the studies…

India’s deadly monsoon rainfall measured with NASA’s IMERG

India's southwest monsoon normally occurs between June and September and is known for being a summertime rainy season. This year's monsoon has been assessed as average but India's Meteorological Department statistics show that daily mean rainfall for the country has recently been above normal. At least 15 people were killed by floods and landslides in India on Wednesday July 11, 2018. So far this year,…

Chemical traces from star formation cast light on cosmic history

A study of intense starbursts - events in distant galaxies in which stars are generated hundreds or thousands of…

The McMaster recipe for star clusters

HAMILTON, ON, June 25, 2018 - Clusters of stars across the vast reaches of time and space of the entire universe were all created the same way, researchers at McMaster University have determined. Researchers Corey Howard, Ralph Pudritz and William Harris, authors of a paper published June 25 in the journal Nature Astronomy, used highly-sophisticated computer simulations to re-create what happens inside gigantic clouds of…

Hawaii telescopes help unravel long-standing cosmic mystery

Astronomers and physicists around the world, including in Hawaii, have begun to unravel a long-standing cosmic mystery. Using a vast array of telescopes in space and on Earth, they have identified a source of cosmic rays--highly energetic particles that continuously rain down on Earth from space. In a paper published this week in the journal Science, scientists have, for the first time, provided evidence for…
