Computer simulations show that the miniature solar flares nicknamed ‘campfires’, discovered last year by ESA’s Solar Orbiter, are likely driven by a process that may contribute significantly to the heating of the Sun’s outer atmosphere, or corona. If confirmed by further observations this adds a key piece to the puzzle of what heats the solar corona – one of the biggest mysteries in solar physics.

• ESA’s second Test-Bed Telescope has seen ‘first light’.
• It will help spot asteroids in space that could pose a risk to Earth.
• This telescope is the latest step towards ESA’s planned Flyeye telescope network.
• It is hosted at the European Southern Observatory’s La Silla Observatory in Chile.

Using the Atacama ALMA array, astronomers found a rotating baby galaxy 1/100th the size of the Milky Way at a time when the Universe was only seven percent of its present age. Thanks to assistance by the gravitational lens effect, the team was able to explore for the first time the nature of small and dark "normal galaxies" in the early Universe, representative of the main population of the firs

NASA is responsible for collecting much of the data that people use to explain humanity's environmental impact on Earth, from documenting climate change and its impacts on ice, sea level and weather patterns, to monitoring the health of forests and the movement of freshwater. But NASA doesn't just report the data. It also acts on it. NASA facilities across the United States are each

North Korean satellites launched into orbit are either unstable or not fully operational, and a reconnaissance satellite launched in February 2016 is not relaying data, a South Korean analyst said. Song Geun-ho, a professor at Korea Defense Language Institute at South Korea's Joint Forces Military University, said in a new report on North Korea's space program that Pyongyang's claims of vi

Northrop Grumman Corporation has been selected by the U.S. Space Force's (USSF) Space and Missile Systems Center (SMC) to proceed with its ongoing Protected Tactical SATCOM (PTS) Rapid Prototype program, with a flight demonstration of the company's PTS payload set to occur in 2024. Selected for the initial award through the Space Enterprise Consortium, this continuation enables Northrop Gr

Not all stars shine brightly all the time. Some have a brightness that changes rhythmically due to cyclical phenomena like passing planets or the tug of other stars. Others show a slow change in this periodicity over time that can be difficult to discern or capture mathematically. KAUST's Soumya Das and Marc Genton have now developed a method to bring this evolving periodicity within the framewo

One of the great mysteries of modern space science is neatly summed up by the view from NASA's Perseverance, which just landed on Mars: Today it's a desert planet, and yet the rover is sitting right next to an ancient river delta. The apparent contradiction has puzzled scientists for decades, especially because at the same time that Mars had flowing rivers, it was getting less than a third
