SpaceX has launched on Wednesday another 60 internet-beaming satellites, bringing the company's constellation to around 480.

One of the 60 Starlink satellites has a visor system installed to block the sun from reflecting off of its communication antenna surfaces. If the system works, it should greatly reduce sunlight reflected off of the satellite back to Earth, one of the major criticisms from astronomers.

Also, this was the fifth launch of the Falcon 9 rocket, achieving a new record in booster reusability for the company.

Study shows erosion of ozone layer responsible for mass extinction event

Researchers at the University of Southampton have found evidence showing high levels of UV radiation, caused by a brief breakdown of the ozone layer, collapsed forest ecosystems and killed off many species of fish and tetrapods in an extinction event at the end of the Devonian geological period, 359 million years ago.

The ozone collapse occurred as the climate rapidly warmed pushing more naturally generated ozone-destroying chemicals into the upper atmosphere. Researchers suggest that the Earth today could reach comparable temperatures, possibly triggering a similar event.

Discovery of Rare Super-Earth at End of Galaxy

A discovery made by University of Canterbury astronomers shows a rare Super-Earth planet near the end of our galaxy. The planet was discovered using gravitational microlensing, a technique that detects planets regardless of the amount of light they emit. The planet's mass and orbit are both similar to that of Earth.
