Introducing Ramses, ESA"s 2029 mission to asteroid Apophis
Thirty years ago, on 16 July 1994, astronomers watched in awe as the first of many pieces of the Shoemaker-Levy 9 comet slammed into Jupiter with incredible force. The event sparked intense interest in the field of planetary defense as people asked:.....»»
Observations detect a nearby hypervelocity stellar/substellar object
Using the Keck II telescope, astronomers have detected an object that may be a brown dwarf or a low-mass star, exhibiting a very high radial velocity. The object, designated CWISE J124909.08+362116.0 is located some 400 light years away. The finding.....»»
Satellite to follow Empire State Building-sized asteroid as it zips by Earth
There’s a huge asteroid coming our way in 2029 and the European Space Agency (ESA) wants to track it every step of the way. Don’t worry, you can look up with confidence, as the 1,230-feet-long (about 375 meters) Apophis asteroid is not on a colli.....»»
Lunar leap: GNSS-powered autonomous navigation for moon-bound spacecraft
As lunar missions gain momentum, the demand for advanced navigation technologies that exceed traditional Earth-based systems grows. A new study addresses the challenges of weak Global Navigation Satellite System (GNSS) signals and spacecraft maneuver.....»»
Astronomers spot a "highly eccentric" planet on its way to becoming a hot Jupiter
Hot Jupiters are some of the most extreme planets in the galaxy. These scorching worlds are as massive as Jupiter, and they swing wildly close to their star, whirling around in a few days compared to our own gas giant's leisurely 4,000-day orbit arou.....»»
Exoplanet caught in "hairpin turn" signals how high-mass gas giants form
Astronomers have discovered a planet that has the most oblong orbit ever found among transiting planets. The exoplanet's extreme circuit—which looks closer to a cucumber than a circle—follows one of the most drastically stretched-out orbits of al.....»»
Astronomers detect dozens of new pulsating white dwarfs
Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have detected 32 new bright pulsating DA white dwarfs of the ZZ Ceti subclass. The finding was reported in a research paper published July 9 on the pre-print server arXiv......»»
Astronomers discover what may be 21 neutron stars orbiting sun-like stars
Most stars in our universe come in pairs. While our own sun is a loner, many stars like our sun orbit similar stars, while a host of other exotic pairings between stars and cosmic orbs pepper the universe. Black holes, for example, are often found or.....»»
Researchers forge more open access data for studies of the Earth"s lithosphere
Crust and lithospheric mantle—the thinnest and thickest layers of the Earth's lithosphere—and a wide range of dynamic processes that deform them can be studied by using high precision geodetic data taken directly from Global Navigation Satellite.....»»
Telescope tag-team discovers 10 strange and exotic pulsars
Towards the center of our Milky Way galaxy, in the constellation Sagittarius, astronomers have discovered 10 monstrous neutron stars. These particular stars, called pulsars, reside together in globular cluster Terzan 5, a crowded home for hundreds of.....»»
Research team uses satellite data and machine learning to predict typhoon intensity
Amidst the challenges posed by climate change in predicting typhoons, a team of researchers has developed a technology that leverages real-time satellite data and deep learning capabilities to predict typhoons with greater precision......»»
Weather satellite passes bake and shake tests with flying colors
As climate change drives more frequent and severe weather events, the need for accurate and timely forecasting has never been more critical. And now, the next Meteosat Third Generation weather satellite has passed its environmental test campaign with.....»»
Scorching storms on distant worlds revealed in new detail
Astronomers have created the most detailed weather report so far for two distant worlds beyond our own solar system. The international study—the first of its kind—reveals the extreme atmospheric conditions on the celestial objects, which are swat.....»»
New low-mass galaxy discovered
Astronomers report the discovery of a new galaxy in the constellation Corvus. The newfound galaxy, which received designation Corvus A, has a relatively low mass, is gas-rich and isolated. The discovery was presented in a research paper published Jul.....»»
How astronomers are using pulsars to observe evidence of dark matter
Tantalizing evidence of potential dark matter objects has been detected with the help of the universe's "timekeepers." These pulsars—neutron stars which rotate and emit lighthouse-like beams of radio waves that rapidly sweep through space—were us.....»»
Saturday Citations: The first Goldilocks black hole; Toxoplasma gondii metabolism; pumping at the speed of muscle
This week: Physicists conducted a biological study, engineers built a waste-recycling suit for astronauts (and worm riders), and astronomers identified the first known intermediate-mass black hole, and it's right here in our own galactic back yard......»»
SpaceX rocket accident leaves company"s Starlink satellites in wrong orbit
A SpaceX rocket has failed for the first time in nearly a decade, leaving the company's internet satellites in an orbit so low that they're doomed to fall through the atmosphere and burn up......»»
SpaceX Falcon 9 rocket experiences rare failure
SpaceX's highly reliable Falcon 9 rocket has experienced a rare failure that means the latest batch of the company's Starlink satellites won't make it into orbit, the company said Friday, as regulators opened an investigation......»»
How astronomers work out the size of the solar system
The size of the solar system is defined by the volume of space over which the sun's influence exceeds those of other nearby stars in the Milky Way galaxy. This influence derives from two fundamental forces of nature: gravity and magnetism......»»
Hubble finds evidence for rare black hole in Omega Centauri
An international team of astronomers has used more than 500 images from the NASA/ESA Hubble Space Telescope spanning two decades to detect seven fast-moving stars in the innermost region of Omega Centauri, the largest and brightest globular cluster i.....»»
