The European Southern Observatory’s Very Large Telescope is in northern Chile. Astronomers used it to capture the unprecedented dimming of Betelgeuse, a red supergiant star in the constellation of Orion. The new images show how the apparent shape of this star is changing.
For the first time, a fast radio burst has been found to be repeating, in a regular 16-day cycle. The baffling detection from the CHIME radio telescope deepens the mystery of these bizarre intergalactic objects.
Solar Orbiter – aka SolO – will take the first direct images of the sun’s poles. Following Sunday’s launch, the spacecraft will take a loopy path through the inner solar system, borrowing thrust from the powerful gravitational fields of Earth and Venus.
A Cygnus resupply spacecraft headed for the International Space Station is scheduled to launch on Sunday, February 9, from Wallops Flight Facility in Virginia. How and when to watch live in the sky, or on NASA TV.

Can you believe it’s been 62 years since the United States launched its 1st satellite? Explorer 1 advanced the space race between the US and the Soviet Union. It led to the discovery of the Van Allen radiation belts.
The clarity of these images from the Daniel K. Inouye Solar Telescope in Hawaii is thanks to the telescope’s 4-meter mirror, the world’s largest for a solar telescope. “It’s the biggest jump in our ability to study the sun since Galileo’s time,” a scientist said.
A new analysis shows that “severe” space super-storms happened 42 years out of the last 150, and “great” super-storms happened 6 years out of 150. These storms can disrupt modern electronics, aviation and satellite systems and communications.
We know our sun is surrounded by a great bubble-like heliosphere, which sets our solar system apart from the rest of interstellar space. ESA’s Solar Orbiter – due to launch in February 2020 – will probe how the sun creates and controls this heliosphere.
