Sommerpodcasttid! Starhopping på sommerhimlen

Jeg har igen været inde i IDA studierne med Tino Tønnesen. Denne gang har jeg talt lidt om at finde rundt på sommerhimlen:

This week (!) is the 30th anniversary of the announcement of 51 Pegasi b, the first exoplanet found orbiting a star like our Sun - since then, we've found over 6,000!

To celebrate, @alexwitze.bsky.social and @nature.com collected some astronomers' favourite planets:

These alien planets are astronomers’ favourites: here’s why
Space scientists look back on 30 years of exoplanet discoveries — from rows of massive ‘super-Earths‘ to worlds with perfectly synchronized orbits.

“We especially need imagination in science. It is not all mathematics, nor all logic, but it is somewhat beauty and poetry.”

Happy #HobbitDay to all!

On 22 September: Bilbo and Frodo Baggins were born. As Ring-bearers, born 78 years apart, their birthdays were honoured as Cormarë, and Tolkien societies worldwide continue to commemorate. How will you celebrate? #Tolkien #BookSky

For tiden kan man på stjernehimlen se "Clash og the Titans" udfolde sig. Det har jeg talt med @nothansolo.bsky.social om i en @ida.dk - Space Talks podcast. 🔭 🇩🇰

OMG YOU GUYS OMGOMGOMG

I found evidence of the possibility that perhaps there’s a slight chance that there could feasibly be a plausible sign that there MAYYYYYY be life on Mars

Potentially

Astronomer Henrietta Swan Leavitt was born #OTD in 1868. She established the period-luminosity relation for Cepheid variable stars, an essential tool for understanding the scale of our Universe. 🧪 👩‍🔬 🔭

The number of working satellites has soared in the past five years to around 11,000, mostly because of constellations of orbiters that provide Internet connectivity around the globe, but it comes with a series of problems. Nature explores the issues and how scientists are reacting. 🔭 🧪
Swarms of satellites are harming astronomy. Here’s how researchers are fighting back
SpaceX and other companies plan to launch tens of thousands of satellites, which could mar astronomical observations and pollute the atmosphere.

Iconic Pillars of Creation.
MIRI + NIRCam composite image.
🔭 🧪
Semi-opaque layers of blue, purple, and grey gas and dust start at the bottom left and rise toward the top right. There are three prominent pillars. The left pillar is the largest and widest. The background is orange near the top and dark blue and purple near the bottom. Some blue and white stars dot the overall scene.

The Pizzable Zone is the region around a star where the temperature is ideal for cooking a pizza (450-500°C). Inner boundary: too hot, pizza burns instantly. Outer boundary: too cool, pizza won't cook properly.

Giant Jet from the International Space Station

What's that on the horizon? When circling the Earth on the International Space Station early last month, astronaut Matthew Dominick saw an unusual type of lightning just beyond the Earth's edge: a gigantic jet. The powerful jet appears on the left of the featured image in red and blue. Giant jet lightning has only been known about for the past 23 years. The atmospheric jets are associated with thunderstorms and extend upwards towards Earth's ionosphere. The lower part of the frame shows the Earth at night, with Earth's thin atmosphere tinted green from airglow. City lights are visible, sometimes resolved, but usually creating diffuse white glows in intervening clouds. The top of the frame reveals distant stars in the dark night sky. The nature of gigantic jets and their possible association with other types of Transient Luminous Events (TLEs) such as blue jets and red sprites remains an active topic of research.

Happy birthday to American #astronomer Henrietta Swan Leavitt (1868-1921) who set the scale of our Universe. 🐡🧪🔭👩🏻‍🔬#histsci In her day, women scientists were regularly hired to do menial chores. She was hired to count images on photographic plates as a "computer". In studying these plates, in 1908 🧵1/
My linocut portrait of Henrietta Swan Leavitt is printed in silvery lavender ink on Japanese kozo (or mulberry paper). Behind her is a line showing stellar luminosity (capital L with subscript sun-symbol, a circle with a dot) as a function of time (t). She is printed over constellations in gold (Cepheus, Cassiopeia, Draco, Ursa Minor and Andromeda). ⁠ ⁠
