Three decades ago, a massive stellar explosion sent shockwaves not only through space but also through the astronomical community. SN 1987A was the closest observed supernova to Earth since the invention of the telescope and has become by far the best studied of all time, revolutionizing our understanding of the explosive death of massive stars.
The New Horizons flyby of Pluto and its satellites returned a scientific treasure trove of information about these distant and surprisingly complex worlds, showing a vast nitrogen glacier as well as ice mountains, canyons, cliffs, craters and more. Now the categories for official names have been approved and the name proposals can be submitted by the New Horizons team.
Bubbles acting like parachutes are deployed by some cosmic dust particles on their entry into Earth’s atmosphere, preventing them from burning up.
Surprising images from the Rosetta spacecraft show the presence of dune-like patterns on the surface of comet Chury. Researchers have studied the available images and modeled the outgassing of vapor to try to explain the phenomenon. They show that the strong pressure difference between the sunlit side of the comet and that in shadow generates winds able to transport grains and form dunes.
New planetary formation models indicate that there may be an undiscovered population of gas giant planets orbiting around Sun-like stars at distances similar to those of Jupiter and Saturn.
The dynamical properties of these asteroids, observed spectroscopiccally for the first time using the Gran Telescopio CANARIAS, suggest a possible common origin and give a clue to the existence of a planet beyond Pluto, the so-called 'Planet Nine.'
New research reveals that the Earth's unique iron composition isn't linked to the formation of the planet's core, calling into question a prevailing theory about the events that shaped our planet during its earliest years.
Sound travels more slowly than light. Then why do sounds of meteors entering Earth's atmosphere precede or accompany the sight of them? Researchers believe they have an answer.
New work shows that interactions between iron and nickel under the extreme pressures and temperatures similar to a planetary interior can help scientists understand the period in our Solar System's youth when planets were forming and their cores were created.
Technically, this picture is merely a sidekick of the actual object of interest -- but space is bursting with activity, and this field of bright celestial bodies offers plenty of interest on its own.
A minor planet in the Solar System will officially be known as Bernardbowen from today after Australian citizen science project theSkyNet won a competition to name the celestial body.
NASA's Dawn spacecraft recently detected organic-rich areas on Ceres. Scientists evaluated the geology of the regions to conclude that the organics are most likely native to the dwarf planet. Data from the spacecraft suggest that the interior of Ceres is the source of these organic materials, as opposed to arriving via impacting asteroids or comets, according to a new article.
A new device has been built to recreate Earth's auroras and other space phenomena in miniature. The planeterrella is one of just a handful in the United States.
This image was taken at 3:38 a.m. EST on Feb. 9, 2017, when the spacecraft was 75 million miles (120 million kilometers) from Earth and 419 million miles (675 million kilometers) from Jupiter. With an exposure time of two seconds, the image renders Jupiter overexposed, but allows for enhanced detection of stars in the background.
Researchers have demonstrated for the first time that it is possible for a planetary collision to form a moon large enough for Kepler to detect. Scientists conducted a series of around 30 simulations to explore how various factors affect moon creation.
The new Space Environment In-Situ Suite (SEISS) instrument onboard NOAA's GOES-16 is working and successfully sending data back to Earth.
The gas cloud from which our solar system formed lasted about 4 million years.
Many scientists believe the Earth was initially dry and that water, carbon and nitrogen -- the building blocks for life -- likely came as a result of collisions with objects that began their lives in the cold outer reaches of our solar system. Today, scientists report discovery of the existence of just such an object -- one that once orbited a neighboring star.
NASA's Magnetospheric Multiscale mission begins a three-month long journey into a new orbit, taking it twice as far out as it has previously flown, to areas where magnetic reconnection is thought to trigger auroras.
For the first time, scientists have witnessed a massive object with the makeup of a comet being ripped apart and scattered in the atmosphere of a white dwarf, the burned-out remains of a compact star.
