We are star stuff. This phrase serves as a gentle reminder that all the complex atom found their start either in the nuclear core of a star or in the nuclear explosions of a dying star or stars. But, as with so many things, the truth is much more complicated than the meme.
Mar 15th: Early Black Holes Formed Before Stars?
We thought stellar mass black holes came from stars and that there might have been tiny primordial black holes that evaporated away, but that was it. Closed case. Black holes formed with all the normal structures we experience today. Except that now, JWST’s observations require us to find a way to accelerate the formation of those structures, and one way to do that is to seed the universe with black holes.
Mar 7th: Yes, Scientists DO Look at the (Dark Energy Survey) Data
Every time I get the digital “why can’t you scientists just look at the data” lecture, I wonder what people think scientists do. All we do is look at data including accelerating rate of expansion of the Universe…
Mar 1st: Celebrating the Mars Robots That Could
Robots on Mars have a long history of exceeding all possible expectations.Today, while we recognize NASA’s Day of Remembrance, we also celebrate all the Mars missions that have done more than expected.
Feb 23rd: The Compass (Sometimes… Kinda) Points North
If you take a compass and follow its pointy little needle, you will end up in Northern Canada but not at the North Pole. If you have a boat, you’ll end up on Ellesmere Island wondering where Santa is hiding. More at #365DaysOfAstro
Feb 16th: Spooky Season Space Images
Throwback from the spooky season: Halloween is, hands-down, the most beloved season of the year. And we have NASA, ESA, ESO, and others releasing their spooky season images. There will be nebulae cropped with the contrast adjusted just so to reveal witches’ hats, and others rotated to reveal ghosts and maybe – I can hope – a goblin or two.
Feb 9th: Making Anti-Matter… Matter
Today EVSN look at what tree rings can teach us about past earthquakes, & how well machine learning can identify life, like trees, from carbon-rich materials that were never alive to distant galaxies and spinning black holes. We even take a deep dive into anti-matter.
Feb 1st: Whales and (Possible) Space Whales
As the Thanksgiving leftovers reach the stage of possibly gaining intelligence in the back of our refrigerators, we’re going to take a look at the origins of life, how we might find simple life on icy moons, and even how we can practice learning to communicate with other civilizations by chatting up a humpback whale.
Jan 26th : Blast From the Past: Watch the Annular Eclipse on October 14!
Today we have a story from the past about how to watch solar eclipse. And also the effects of spawning anchovies on energy dissipation in the ocean. Along with that fishy story, we have news from the Mars rovers, pretty images.
Jan 19th: Solar Cycle to the Maximum, 2025
Solar maximum will occur sometime in late 2024 to early 2025. With this cycle and the satellite will experience a good blast of solar radiation. Including the small sats, CanSats.
