A number of research projects will take place across the country during the upcoming Aug. 21 solar eclipse. The research will advance our knowledge of the sun's complex and mysterious magnetic field and its effects on Earth's atmosphere and land.
The gravitational dance between two galaxies in our local neighbourhood has led to intriguing visual features in both as witnessed in this new NASA/ESA Hubble Space Telescope image. The tiny NGC 1510 and its colossal neighbour NGC 1512 are at the beginning of a lengthy merger, a crucial process in galaxy evolution. Despite its diminutive size, NGC 1510 has had a significant effect on NGC 1512's structure and amount of star formation.
Astronomers have discovered 23 young galaxies, seen as they were 800 million years after the Big Bang.
Gamma-ray bursts are among the most energetic and explosive events in the universe. They are also short-lived, lasting from a few milliseconds to about a minute. This has made it tough for astronomers to observe a gamma-ray burst in detail. Using a wide array of ground- and space-based telescope observations, astronomers constructed one of the most detailed descriptions of a gamma-ray burst to date.
There are about seven times more long-period comets measuring at least 1 kilometer across than previously predicted, suggests new research. The researchers also found that long-period comets are, on average, nearly twice as large as 'Jupiter family' comets, whose orbits are shaped by Jupiter's gravity and have periods of less than 20 years.
New maps of dark matter dynamics in the Universe have been produced by a team of international cosmologists, outlines a new report.
Astronomers shed light on the so far unexplored nightside circulation at the upper cloud level of Venus. Researchers have discovered unexpected patterns of slow motion and abundant stationary waves in Venus's nighttime sky.
A team of scientists will take to the skies during the Aug. 21 eclipse, using two of NASA's WB-57 jet planes to chase the shadow of the moon for unparalleled observations of the sun and Mercury.
A solar eclipse will be visible across North America for 2 to 3 hours on Monday, August 21, 2017. Watching the moon slowly block out the sun is a rare opportunity but should be attempted with caution.
NASA's Van Allen Probes have observed a new population of space sound waves, called plasmaspheric hiss, which are important in removing high-energy particles from around Earth that can damage satellites.
The death of a massive star in a distant galaxy 10 billion years ago created a rare superluminous supernova, one of the most distant ever discovered. The brilliant explosion, more than three times as bright as the 100 billion stars of our Milky Way galaxy combined, occurred about 3.5 billion years after the big bang at a period known as 'cosmic high noon,' when the rate of star formation in the universe reached its peak.
In the lead-up to a total solar eclipse, most of the attention is on the sun, but Earth's moon also has a starring role.
A web that passes through infinite intergalactic spaces, a dense cosmic forest illuminated by very distant lights and a huge enigma to solve. These are the picturesque ingredients of a scientific research that adds an important element for understanding one of the fundamental components of our Universe: dark matter.
Engineers say a method called digital holographic microscopy could be used to detect living microbes in space.
It was midafternoon, but it was dark in an area in Boulder, Colorado on Aug. 3, 1998. A thick cloud appeared overhead and dimmed the land below for more than 30 minutes. Well-calibrated radiometers showed that there were very low levels of light reaching the ground, sufficiently low that researchers decided to simulate this interesting event with computer models. Now in 2017, inspired by the event in Boulder, NASA scientists will explore the moon's eclipse of the sun to learn more about Earth's energy system.
The international Spitzer Adaptation of the Red-sequence Cluster Survey (SpARCS) collaboration has combined observations from several of the world's most powerful telescopes to carry out one of the largest studies yet of molecular gas -- the raw material which fuels star formation throughout the universe -- in three of the most distant clusters of galaxies ever found, detected as they appeared when the universe was only four billion years old.
While photographing Mars, NASA's Hubble Space Telescope captured a cameo appearance of the tiny moon Phobos on its trek around the Red Planet. Hubble took 13 separate exposures over 22 minutes to create a time-lapse video showing the moon's orbital path.
Astronomers have provided a way for armchair astronomers, and even primary school children, to merely look at a spiral galaxy and estimate the mass of its hidden, central black hole.
The center of our Milky Way contains a 'trap' that concentrates some of the highest-energy cosmic rays, among the fastest particles in the galaxy, a combined analysis of data from NASA's Fermi Gamma-ray Space Telescope and the High Energy Stereoscopic System, a ground-based observatory in Namibia, suggests.
The Neutron star Interior Composition Explorer, or NICER, payload completed commissioning and calibration and all systems are working as expected.
