Elon Musk's Starlink satellites are already giving astronomers a headache

Astronomers at a Chilean observatory were roughly interrupted earlier this week when a SpaceX satellite train consisting of 60 Starlink satellites floated above their heads, which scientists seem to have accepted as a new normality. The Starlink-Smallsat train launched into orbit on November 11 crossed the Interamerican Observatory of Cerro Tololo in Chile astronomer Clarae for five minutes Martínez-Vázquez. "Wow …

Starlink satellites pose problems for astronomers

Watching satellites from the ground is a popular pastime among amateur astronomers. Typically, the ISS and Iridium satellites were widely used because their orbits and design make them appear sufficiently bright in the sky. More recently SpaceX's mass launches of Starlink satellites have attracted attention for the wrong reasons . A photograph of the Cerro Telolo Observatory shows the many …

Astronomers detect water vapor around Jupiter's moon Europa

In search of life in our solar system, Mars steals the spotlight (thanks, David Bowie). In recent years, Jupiter's fourth largest moon, Europe, has become a promising alien kindergarten. Planet scientists have long suspected that Europe under its thick, icy crust harbors a huge ocean of liquid water. If the ocean of Europe also has an energy source – think …

The Starlink problem that astronomers were worried about is in full swing

For modern astronomers, satellites are only a part of life. There are more than 2,000 active people orbiting the Earth, and the brightest minds in space photography have managed to remove the occasional overflights from their space imagery. But then there is Starlink. The first phases of the SpaceX plan to launch up to 42,000 satellites to fully power the …

Why SpaceX wants to put 25,000 satellites into orbit is bad news for astronomers

It is a truism that the commercialization of science is often detrimental. The Internet, once a commercial-free academic and intellectual space, has been turned into a digital billboard. Similarly, the commercialization of radio waves has made terrestrial radio astronomy more difficult due to interference from WLAN, AM / FM and TV signals. Now, as the capitalists prepare for the commercialization …

Is this asteroid the smallest planet? Some astronomers believe it.

An asteroid orbiting the Sun surprised astronomers by turning out to be roughly spherical – possibly the smallest dwarf planet in the solar system, according to a study by an astronomical team. The asteroid, called Hygeia, is the fourth largest object orbiting in the asteroid belt between Mars and Jupiter, after the dwarf planet Ceres and the asteroids Vesta and …

Why astronomers worry about the brightness of SpaceX's Starlink satellite mega-constellation

SpaceX plans to launch the second episode of its mega-constellation Starlink on Monday (November 11), and astronomers are waiting to see – exactly what they'll see. When the company launched its first set of Starlink Internet satellites in May. Those with their eyes fixed on the night sky immediately noticed that the objects were incredibly bright. Professional astronomers feared the …
