Dutch UFO spotters freak out over satellites

Filed under: General,Weird by Orangemaster @ 8:58 pm


Dutch UFO reporting website was swamped with more than 150 sightings, with fervent UFO spotters describing a “bizarre train of stars or lights moving across the skies at constant speed”.

Instead of anything alien, it was a string of some 60 satellites launched by businessman Elon Musk’s SpaceX hours earlier as part of its ‘Starlink’ constellation. A lot of Dutch folks staring at the sky had no clue this was going to happen, so you can imagine the commotion it caused.

One of SpaceX’s Falcon 9 rockets blasted off from Cape Canaveral in Florida last Friday, and an hour later began releasing the satellites at an altitude of 450 kilometres. The satellites then had to separate and use their thrusters to take up their positions in a relatively low orbit of 550 kilometres. Starlink will become operational once 800 satellites have been activated, which will require a dozen more launches.

Dutch astronomer Marco Langbroek noted on his blog that he calculated where the satellites would be orbiting, and waited with his camera. The result is a spectacular one: a string of bright dots flying across the sky, prompting people to report UFOs.

Here is Langbroek video of the event:

Dutch stumble upon possible toddler planet

Filed under: Science by Orangemaster @ 10:32 am


During a look up in the sky, an international group of astronomers headed by Dutch researchers from Leiden University may have found a ‘growing’ planet.

The astronomers were examining the dust disc around the young double star CS Cha when they saw a small dot on the edge of their images, which turned out to be a small planet of only ‘a few million years young that moves along with the double star. CS Cha and its special companion are located some 600 light years away from earth in a star formation area in the southern constellation Chameleon.

In the future, the researchers want to examine the star and the companion in more detail using the international ALMA telescope on the Chajnantor plateau in the North Chilean Andes.

Vampire stars suck the life out of bright stars

Filed under: Science by Orangemaster @ 10:58 am

Hugues Sana of the University of Amsterdam explains that the brightest stars in the universe are getting the life sucked out of them by vampire stars, also called O stars. According to researchers, a third of the vampire-victim pairs are eventually expected to merge and become one.

“These stars are absolute behemoths,” said Sana, lead author of this study. “They have 15 or more times the mass of our Sun and can be up to a million times brighter. These stars are so hot that they shine with a brilliant blue-white light and have surface temperatures over 54,000 degrees Fahrenheit.”
