China's programme to launch a mission to Mars in 2020 is "well underway", its top planner said Wednesday as the country moves forward with its ambitious space programme.
The International Space Station's Joe Acaba (AH-kah-bah), the first astronaut of Puerto Rican heritage, has been affected by two hurricanes—even in orbit.
While people protect their eyes from the sun's radiation during a solar eclipse, NASA's Human Research Program (HRP) is working to protect the whole human body from radiation in space. Space radiation is dangerous and one of the primary health risks for astronauts.
Space enthusiasts are invited to become scientists to help identify massive solar eruptions by watching video clips recorded in space.
The spectacular aurora borealis, or the "northern lights," over Canada is sighted from the International Space Station near the highest point of its orbital path. The station's main solar arrays are seen in the left foreground.
Astronomers have used ALMA to capture a strikingly beautiful view of a delicate bubble of expelled material around the exotic red star U Antliae. These observations will help astronomers to better understand how stars evolve during the later stages of their life-cycles.
Cassiopeia A is a famous supernova remnant, the product of a gigantic explosion of a massive star about 350 years ago. Although discovered in radio observations 50 years ago, we now know that its emitted radiation spans from radio through high-energy gamma rays. Show More Summary
Astrophysicists from Moscow State University have found a new way to estimate the mass of supermassive black holes outside our galaxy, even if they are barely detectable. The results of the study were published in Astronomy and Astrophysics.
Employing an array of giant telescopes positioned in the New Mexico desert, astronomers have started a massive surveying project aimed at producing the most detailed view ever made of such a large portion of space using radio waves emitted from throughout the Milky Way and beyond.
The scorching hot surface of Mercury seems like an unlikely place to find ice, but research over the past three decades has suggested that water is frozen on the first rock from the sun, hidden away on crater floors that are permanently shadowed from the sun's blistering rays. Show More Summary
During almost four years of observing the cosmos, the Herschel Space Observatory traced out the presence of water. With its unprecedented sensitivity and spectral resolution at key wavelengths, Herschel revealed this crucial molecule...Show More Summary
Small satellites provide a cheap, responsive alternative to larger, more expensive satellites. As demand grows, engineers must adapt these "nanosatellites" to provide greater data returns. NASA, in collaboration with educational partners, targets 2021 for the launch of an innovative CubeSat that addresses these challenges.
A fleet of tiny spacecraft could visit over 300 asteroids in just over three years, according to a mission study led by the Finnish Meteorological Institute. The Asteroid Touring Nanosat Fleet concept comprises 50 spacecraft propelled...Show More Summary
The mining of resources contained in asteroids, for use as propellant, building materials or in life-support systems, has the potential to revolutionise exploration of our Solar System. To make this concept a reality, we need to increase our knowledge of the very diverse population of accessible Near Earth Asteroids (NEA). Show More Summary
A group analysis of 30 exoplanets orbiting distant stars suggests that size, not mass, is a key factor in whether a planet's atmosphere can be detected. The largest population-study of exoplanets to date successfully detected atmospheres around 16 'hot Jupiters', and found that water vapour was present in every case.
At more than 10 billion miles away from Earth, there is no day and night. Time and space are fathomless and our Sun is a distant point of starlight—a faint reminder of the home NASA's twin Voyagers, humanity's farthest and longest-lived spacecraft, left behind 40 years ago. Show More Summary
It was a proud but sad moment when NASA announced that mission control had lost the signal from the Cassini spacecraft on September 15. As it takes the signal over an hour to travel from Saturn to Earth, this meant that the spacecraft had already been destroyed in Saturn's atmosphere.
(Phys.org)—A team of astronomers led by Jacob M. Robertson of the Austin Peay State University in Clarksville, Tennessee has detected a new quasi-stellar object (QSO). They found the new quasar, designated SDSS J022155.26-064916.6, as a result of an analysis of available spectroscopic data. The finding is reported in a paper published Sept. 10 on the arXiv pre-print server.
Radio astronomy is undergoing a major boost, with new technology gathering data on objects in our universe faster than astronomers can analyse.
Could the flapping of a butterfly's wings in Costa Rica set off a hurricane in California? The question has been scrutinized by chaos theorists, stock-market analysts and weather forecasters for decades. For most people, this hypothetical scenario may be difficult to imagine on Earth - particularly when a real disaster strikes.
