So how does a star become a black hole? Journey inside a black hole — and the processes that create them — with the latest episode of @NASA’s Curious Universe podcast: #BlackHoleFriday

Some stars end their lives as black holes — but our star, the Sun, is too small for such a fate. Instead, the Sun will eventually expand into a red giant before collapsing into a stellar remnant called a white dwarf. #BlackHoleFriday

Stuffing ingredients:
☑️ Bread
☑️ Celery
☑️ Onion
◻️ ...Hydrogen?

New evidence from NASA’s New Horizons spacecraft suggests that nearby interstellar space is stuffed with about 40% more hydrogen than previously thought. #Thanksgiving

Energized particles & electromagnetic fields in space create an intense, hard-to-predict radiation environment — one that can threaten astronauts and electronics. Two instrument suites on the lunar Gateway will monitor these conditions at the Moon.

Over the course of nearly 25 years, @ESA and @NASA’s SOHO solar observatory has found more than 4,000 previously unknown comets — a result of well-designed instruments, a long lifespan, and the work of countless citizen scientists. ☄️

The exact origins of the aurora-like STEVE have eluded scientists since the first research on this phenomenon was published in 2018. Now, observations from citizen scientists — who were also instrumental in the original discovery — are giving new clues.

Even astronauts need to check the weather before they travel. 👩🏼‍🚀☔ For #Artemis astronauts, @NASA and @ESA instrument suites on board the lunar Gateway will provide an early space weather forecast.

The #ParkerSolarProbe team has released a new batch of science data, collected this summer during the spacecraft’s 5th solar flyby. In 2021, Parker Solar Probe will complete 4 solar flybys and 2 Venus gravity assists. More on what’s next for the mission:

Measurements from NASA’s New Horizons mission are revising our estimates of a key property of the space between the stars: how thick it is. New findings show that the local interstellar medium contains about 40% more hydrogen atoms than previously thought.

This makes me smile big! 😊 A new @ESA/@NASASun SOHO comet discovered today by *12-YR OLD* @RafalBiros! It's his 1st SOHO comet, and makes him the youngest SOHO comet discoverer... perhaps the youngest comet discoverer ever?! Huge congrats!! 🎉

That's how you @DoNASAScience!👏

12 years old and already discovering comets. How very cool! Congrats and thank you!

Citizen scientists were instrumental in discovering the aurora-like STEVE phenomenon. Now, their observations are a key part of new research that moves scientists one step closer to understanding the mysterious origins of STEVE.

A host of factors go into making a world habitable — or not. Even under a relatively friendly star like our Sun, the worlds in our solar system have a range of conditions for hosting potential life. Meet the neighbors:

Did you know that the solar cycle has been regularly recorded by hand since 1755? In fact, some sunspot measurements date as far back as 3,000 years ago!
