Square Kilometer Array 12 Sep 2019, 08:00 UTC An international team of astronomers using South Africa’s MeerKAT radio telescope has discovered enormous balloon-like structures that tower hundreds of light-years above and below the centre of our galaxy.
NASA's Chandra X-ray Observatory 11 Sep 2019, 17:22 UTC A supermassive black hole is blasting out X-rays about every nine hours, according to data from NASA's Chandra X-ray Observatory and ESA's XMM-Newton, as described in our latest press release. This indicates that this black hole, containing about 400,000 times the mass of our Sun, is consuming significant amounts of material about three times per day.

ESA Top News 10 Sep 2019, 19:13 UTC Things got heated on the International Space Station this week after the Multiscale Boiling experiment, known as Rubi, was successfully switched on. ESA astronaut Luca Parmitano installed the shoe box-sized container studying the boiling process in the Fluid Science Laboratory of the Columbus module after its arrival on a Dragon cargo resupply mission in August.
NASA's Jet Propulsion Laboratory News and Features 9 Sep 2019, 15:02 UTC Using radar data from NASA's Cassini spacecraft, recently published research presents a new scenario to explain why some methane-filled lakes on Saturn's moon Titan are surrounded by steep rims that reach hundreds of feet high. The models suggests that explosions of warming nitrogen created basins in the moon's crust.

ESA Space Science 9 Sep 2019, 08:44 UTC By studying the rocks inside impact craters like this one, ESA research fellow Joana S. Oliveira has found that the location of Mercury’s magnetic field has changed over time in surprising ways. Just like Earth, Mercury has a liquid metallic core, the motions within generating the magnetic field. On Earth, our magnetic north and south poles drift between about 10 and 60 km per year, with our planet’s magnetic field orientation flipping more than 100 times in the course of its 4.5 billion years.
NASA's Goddard Space Flight Center 6 Sep 2019, 19:00 UTC A key tracer used to estimate how much atmosphere Mars lost can change depending on the time of day and the surface temperature on the Red Planet, according to new observations by NASA-funded scientists. Previous measurements of this tracer – isotopes of oxygen – have disagreed significantly. An accurate measurement of this tracer is important to estimate how much atmosphere Mars once had before it was lost, which reveals whether Mars could have been habitable and what the conditions might have been like.
