There is a strong relation between the size of a galaxy's black hole and the motion of stars in the galaxy's core, known as the M-sigma relation. It turns out this relation doesn't work well for galaxies with ultramassive black holes.

A scientific balloon starts its ascent into the air as it prepares to launch carrying NASA’s Payload for Ultrahigh Energy Observations (PUEO) mission. The mission lifted off from Antarctica at 5:56 a.m. NZST, Saturday, Dec. 20 (11:56 a.m., Friday, Dec. 19 in U.S. Eastern Time). The PUEO mission is designed to detect radio signals created when highly energetic particles called neutrinos from space hit the ice.

Media representatives joined French ESA astronaut Sophie Adenot, on Monday 5 January, for a hybrid press conference to learn more about her first mission to space.

This event, held at the European Astronaut Centre (EAC) in Germany, was the final media event in Europe ahead of her launch to the International Space Station.

Sophie selected the name ‘εpsilon’ for her first mission, currently planned no earlier than 15 February, reflecting the power of small, yet impactful contributions, and how many parts come together to make a whole.

During εpsilon, Sophie will conduct a wide range of tasks on the International Space Station, including European-led scientific experiments, medical research, supporting Earth observation and contributing to operations and maintenance on the Station.

For years, we've thought of autism as lying on a spectrum, but emerging evidence suggests that it comes in several distinct types. The implications for how we support autistic people could be profound

A galaxy cluster in the early universe is 10 times hotter than it ought to be, which may reshape how we think these enormous structures formed

The US government is approving the drug leucovorin to address rising rates of autism, despite limited evidence that it works. This year, results from the largest trial yet should give more insight into its potential

Many less massive galaxies appear to lack something astronomers thought was ubiquitous: a central, supermassive black hole.

The post Not Every Galaxy Has a Central Black Hole appeared first on Sky & Telescope.

So far, humanity has yet to find its first “exomoon” - a Moon orbiting a planet outside of the solar system. But that hasn’t been for lack of trying. According to a new paper by Thomas Winterhalder of the European Southern Observatory and his co-authors available as a pre-print on arXiv, the reason isn’t because those Moons don’t exist, but simply because we lack the technology to detect them. They propose a new “kilometric baseline interferometer” that can detect moons as small as the Earth up to 200 parsecs (652 light years) away.
