The bright BlueWalker 3 satellite, a prototype for the even larger Bluebird satellites, is one of the brightest objects in the sky.
Satellites’ leakage radiation, now detected for the first time, may become a major problem for radio astronomy, as “megaconstellations” keep on growing.
Despite being four times larger than the original Starlink satellites, the new "Mini" version is fainter — as dim as astronomers have recommended such satellites be.
Astronomers are sounding the alarm about low-Earth orbit satellites and space debris as significant contributors to light pollution that will affect even the remotest earthbound stargazer.
The imminent launch of a BlueWalker satellite, with a giant phased array antenna, portends a brightening night sky. Amateur astronomers can help record these changes with the goal of mitigating them.
Changes to the design of Starlink satellite spacecraft have made them brighter again, though still dimmer than the original design.
A minor space storm took down much of the latest Starlink batch shortly after launch.
What seemed a lucky break — the discovery of a gamma-ray burst in the most distant known galaxy — might instead be the flash of passing space debris. As satellites fill low-Earth orbit, such events might become common.
Measurements of Starlink's "VisorSat" show SpaceX has succeeded in making a less reflective satellite. But it's still visible from dark-sky areas.
Concerns about the night sky remain as the fourth batch of Starlink satellites — and the second one to be launched within the span of a month — takes flight.
A second set of 60 Starlink satellites take to space, amid promise and controversy.
While the growing number of satellites above our heads is a concern, there are ways to mitigate their appearances in deep-sky astrophotography.
