DENVER – Two young brothers and their cousin were wandering through a fossil-rich stretch of North Dakota’s badlands when they made a discovery that left them “completely speechless”: a T. rex bone sticking out of the ground. The trio publicly announced their discovery Monday during a Zoom news conference, as workers at the Denver Museum … Read more
We’ve received a strange signal from across the galaxy, and astronomers are struggling to understand what it means. They know what is sending the signals. It is a neutron star called ASKAP J193505.1+214841.0 (ASKAP J1935+2148 for short), located in the plane of the Milky Way, about 15,820 light-years from Earth. But the signals themselves are … Read more

Enlarge / A slowly rotating neutron star is still our best guess as to the source of the mysterious signals. About a year ago, astronomers announced that they had observed an object that should not exist. Like a pulsar, it sent out regularly timed bursts of radio emissions. But unlike a pulsar, there were more … Read more

SpaceX and AST SpaceMobile are working to bring satellite connectivity to smartphones, but scientists say the technology threatens to disrupt radio astronomy. “The proposed direct-to-cell satellites would effectively eliminate the existence of radio silence zones, significantly reducing the effectiveness of existing radio telescopes,” said Catherine Lovekin, associate professor of physics at Mount Allison University in … Read more
Earth is expected to be hit by a powerful three-day solar storm today that could cause “fluctuations in the power grid,” experts warn. The National Oceanic and Atmospheric Administration (NOAA) noted that the geomagnetic storm, which is a major disruption of Earth’s magnetosphere, could disrupt the orbits of satellites, cause radio blackouts and create incredible … Read more
A powerful solar flare has spewed from the same sunspot that produced the spectacular Northern Lights displays on May 10. The May 29 solar flare was measured as a class X1.4 eruption, one of the most powerful types of solar flares, and caused radio blackouts in the US and Western Europe. The sunspot that caused … Read more
