Northrop Grumman’s Cygnus spacecraft is preparing to end a roughly 40-hour journey playing catchup with the International Space Station. After launching late Sunday morning from Cape Canaveral Space Force Station on a SpaceX Falcon 9 rocket, the spacecraft is targeting its arrival at the orbiting outpost Tuesday morning.
Mention the name Starlink among the astronomy community and you will often be greeted with a shudder. There are now thousands of Starlink satellites orbiting Earth providing internet connectivity to every corner of the Earth. Many believe they are making astronomy difficult but now, SpaceX is launching another service; ‘direct-to-cell’ technology that will allow mobile phones to use satellites to send text messages as early as this year. Voice and data services are likely to follow on quickly next year. With smaller antennae at a lower altitude what is their impact on astronomy?
Northrop Grumman's robotic Cygnus freighter reached the ISS early Tuesday morning (Aug. 6), carrying about 4 tons of supplies to the orbiting lab.
The SpaceX Dragon Freedom spacecraft is pictured docked to the space-facing port on the International Space Station’s Harmony module. Dragon Freedom carried four Axiom Mission-2 astronauts to the orbital lab on May 22, 2023, including Commander Peggy Whitson, Pilot John Shoffner, and Mission Specialists Ali Alqarni and Rayyanah Barnawi.

Ten neutron stars found lurking in the Milky Way include cosmic black widows killing stars with "webs" of viscous plasma and a speed demon that spins over 700 times per second.
Add another pair of strong solar flares to the sun's list this year, as two X-class flares erupted on Monday morning (Aug. 5).
Modern astronomy would struggle without AI and machine learning (ML), which have become indispensable tools. They alone have the capability to manage and work with the vast amounts of data that modern telescopes generate. ML can sift through large datasets, seeking specified patterns that would take humans far longer to find.

Over 5,000 exoplanets have been discovered around distant star systems. Protoplanetary disks have been discovered too and it’s these, out of which all planetary systems form. Such disks have recently been found in two binary star systems. The stellar components in one have a separation of 14 astronomical units (the average distance between the Earth and Sun is one astronomical unit) and the other system has a separation of 22 astronomical units. Studying systems like these allow us to see how the stars of a binary system interact and how they can distort protoplanetary disks.

The sun could collect rogue planets and hold them at the outskirts of the solar system for millions of years, occasionally trading them with neighboring star Alpha Centauri.
Here's how to see a dazzlingly bright Venus, an eerie view of Earthshine and the peak of the Perseid meteor shower, this week.
Amateur astronomers are all life-long learners — and this "back to school" time of year provides just the right motivation.

Atmospheric nitrogen dioxide is a harmful pollutant with significant impacts on air quality, climate and the biosphere. Although satellites have mapped nitrogen dioxide concentrations since the 1990s, their resolution was generally too coarse to pinpoint individual sources like power plants.
