A video taken by amateur astronomer Matthijs Burgmeijer shows a comet with the potential to become visible to the naked eye in just a few weeks streaking brightly across a background of stars.

Why it matters: The comet — named Comet C/2019 Y4 (ATLAS) — was discovered in December and since then has brightened beautifully as it started to fly closer to the Sun.

OneWeb's bankruptcy, announced Friday, could mark the beginning of a shakeout for companies hoping to make a profit using constellations of small satellites to beam internet to people on Earth.

The big picture: Analysts have been concerned that the market for satellite internet likely can't support more than one or two companies aiming to develop these constellations.

In the last year, countries including the U.S., France, Russia and Japan took steps toward further militarizing their uses of outer space, according to a new report from the Secure World Foundation.

Why it matters: As space becomes increasingly key for militaries, nations are starting to find new ways to protect their military and research satellites, raising concerns that they might develop ways of destroying enemy satellites and making some parts of space unusable.

Data from Earth-gazing satellites is key for scientists hoping to understand and track disease outbreaks including the unfolding coronavirus pandemic.

Why it matters: A satellite's view can allow health researchers to understand the context of an outbreak in a way other tools cannot, and it has the potential to help scientists predict when and where the next infectious disease outbreak may occur.
