Researchers from Keele University have worked with an international team of astronomers to find for the first time that a white dwarf and a brown dwarf collided in a 'blaze of glory' that was witnessed on Earth in 1670.

Atacama Large Millimeter/submillimeter Array (ALMA) in Chile observed the debris from the explosion

This is the first time such an event has been conclusively identified

The dual rings of dust and gas - the debris from the explosion - resemble an hourglass

NASA's Aqua satellite passed over the Central Atlantic Ocean and obtained infrared data on Leslie, now weakened to a large tropical storm.

The National Hurricane Center or NHC said that Leslie remains a large tropical storm, with tropical-storm-force winds extending outward up to 290 miles (465 km) from the center. Because of the size and strength of Tropical Storm Leslie, waves from Leslie are expected to increase along the coasts of Atlantic Canada and New England today, Oct. 5.

The Global Precipitation Measurement mission or GPM core satellite passed over Tropical Storm Kong-Rey and analyzed the rates in which rain was falling throughout the storm.

At the time GPM passed overhead, GPM's Microwave Imager (GMI) instruments collected data that revealed moderate convective rainfall northwest of Kong-Rey's center. GPM indicated that rain was falling at over 1.8 inches (45.7 mm) per hour within two areas of storms northwest of Kong-Rey's center.

Taking advantage of observations from the Hubble Space Telescope, researchers provide evidence of what could be the first exomoon - a moon orbiting a planet outside our solar system. While the authors were rigorous in their evaluations, they caution that their results must be confirmed by subsequent work. Recently, NASA's Kepler space telescope surveyed for moons in a sample of 284 transiting planets - planets that pass between a star and an observer, resulting in a momentary dimming of the star's light.

One of the weirdest objects in the Milky Way just got weirder. Scientists have discovered a new source of the highest-energy photons in the cosmos: a strange system known as a microquasar, located in our neck of the galaxy a neighborly 15,000 light years from Earth. The discovery could shed light on some of the biggest, baddest phenomena in the known universe.

Bombing raids by Allied forces during the Second World War not only caused devastation on the ground but also sent shockwaves through Earth's atmosphere which were detected at the edge of space, according to new research. University of Reading researchers have revealed the shockwaves produced by huge bombs dropped by Allied planes on European cities were big enough to weaken the electrified upper atmosphere - the ionosphere - above the UK, 1000km away. The results are published today in the European Geosciences Union journal Annales Geophysicae.

On Sept. 9, 2018, NASA's Solar Dynamics Observatory, SDO, saw two lunar transits as the Moon passed in front of the Sun. A transit happens when a celestial body passes between a larger body and an observer. This first lunar transit lasted one hour, from 4:30 pm to 5:30 p.m. EDT and obscured 92 percent of the Sun at the peak of its journey. The second transit happened several hours later at 9:52 p.m. and lasted a total of 49 minutes, ending at 10:41 p.m. EDT. This transit only obscured 34 percent of the Sun at its peak.

Astronomers from the Department of Physics at the University of Tokyo discovered a dense disk of material around a young star, which may be a precursor to a planetary system. Their research could vastly improve models of how solar systems form, which would tell us more about our own place in the cosmos.

The conditions for life surviving on planets entirely covered in water are more fluid than previously thought, opening up the possibility that water worlds could be habitable, according to a new paper from the University of Chicago and Pennsylvania State University.

For centuries, scientists have worked to understand the makeup of Jupiter. It's no wonder: this mysterious planet is the biggest one in our solar system by far, and chemically, the closest relative to the Sun. Understanding Jupiter is a key to learning more about how our solar system formed, and even about how other solar systems develop.

But one critical question has bedeviled astronomers for generations: Is there water deep in Jupiter's atmosphere, and if so, how much?
