Bij onze vragenservice komen per jaar zo'n 3000 vragen binnen van mensen die willen weten wat ze in de natuur hebben gezien of gevonden. Vaste prik daarbij: mensen die hopen dat ze een meteoriet hebben opgedoken. Met officieel 6 meteorieten in heel Nederland ooit is het antwoord altijd 'nee'

De werkgroep die zich ermee bezig houdt, heeft overigens een mooi stroomdiagram over deze vraag: werkgroepmeteoren.nl/meteoriet-of...

#ESOjobs We are inviting students from European and Chilean Universities in their career's last period to participate in the Winter Internship 2026 programme at Paranal. The deadline to apply is 28 February 2026. Details: https://recruitment.eso.org/ 📷 ESO/G.Hüdepohl (atacamaphoto.com)

De #Zon momenteel. De grote zonnevlekkengroep linksboven (AR4366) heeft zich razendsnel ontwikkeld en is heel actief geworden. Om in de gaten te houden voor eventueel noorderlicht. Halo om de #Maan vannacht, met rechtsboven de planeet #Jupiter.

Longer duration X1.6 solar flare observed around AR 4366 peaking at 08:13 UTC (Feb 2). A further update will be provided later if a CME is associated. SolarHam.com

AR4366 is lekker bezâg!

News of plans for *another* mega constellation yesterday. Amateur astronomers: get out there & look at the stars any chance you get, no matter how tired you are, because the night sky we love will be gone soon, hidden behind a wall of billionaires' WiFi routers.

Attn news commentators: Trump saying he could use force to obtain Greenland but won’t is not Trump saying he won’t use force to obtain Greenland. It is Trump using force as a threat to obtain Greenland. That is why he mentions it.

Dit is Gidi Markuszower. De man die expliciet opriep om Tweede Kamerleden te berechten in tribunalen. Het is ontluisterend dat D66 überhaupt overweegt om deals met hem te sluiten. Deze tijd vraagt om verzet tegen extreem-rechts, ook als je op zoek bent naar steun voor je minderheidskabinet.

Great aurora visible in Dwingeloo yesterday!

Hier nog wat kiekjes van het #noorderlicht van gisteren, op de Purmerringdijk in Purmerend. Vanavond weer? Ik verwacht van niet, maar ik ben wel mijn sd-kaarten aan het leegtrekken en de batterijen aan het opladen ;)

Gisteren gemist en/of wil je meer van dat? In dit blogje leg ik uit hoe je zelf kunt beoordelen of er #noorderlicht op komst is: www.oetie.nl/astronomie/z...

An absolutely awesome display of Northern Lights over the Netherlands during the past hour! Red glow in the North and a green curtain passing over whose motion was very obvious with the naked eye. This is 1 hour worth of 15 second exposures with my all sky camera from 21to 22UTC. #auroraBorealis

Fantastic #aurora tonight. Even from my city garden at 52.25 north you could see fast moving green bands and red clouds with the unaided eye. @leonoor.bsky.social @waddensky.nl @petervogel.bsky.social @tamithaskov.bsky.social

Aaaaaa noorderlicht in de achtertuin in Purmerend aaaaaaa

Faint, red aurora is already appearing on the northern horizon as seen from Germany. Views will probably strengthen over the next 1-2 hours. theauroraguy.com/pages/webcams

Latest NASA CME model: CME may be FASTER than originally anticipated. Impact is slated for Jan 20 around 1 UT--it's a very fast CME and could deliver strong geomagnetic storming Monday night with auroras visible across mid-latitudes. We'll see what happens over the next 24 hr! #heliophysics

X marks the spot—💥☀️ kaboom! Sunspot region AR4341 just unleashed a powerful X1.95 flare, instantly boosting solar activity to high levels🚀. It’s still too early to say for sure, but early imagery hints at a possible coronal mass ejection (CME) 🌬️ headed outward. Stay tuned! 👀✨ bit.ly/sunactivity

A FULL-HALO CME is emerging in coronagraph imagery. The CME looks to be biased a bit to the east of Earth, but the shock front may clip us. The CME is not *directly* aimed at Earth, but we may receive a glancing blow. Now we wait for model releases and arrival time predictions...

Astronomer Elisabetha Hevelius was born 379 years ago today. She married astronomer Johannes Hevelius at 16, and after his death it was she who published the Prodromus Astronomiae in 1690, a rigorously computed collection of 1564 star positions. #WomenInSTEM #AstroSky 🧪🔭

Did you know that there is a lunar crater named after Anton Pannekoek? It's at the far side of the moon so we can't see it through a telescope from earth. This photo was taken by the Lunar Reconnaisance Orbiter. What's your favourite lunar feature? 🌔🔭

#OnThisDay in 1610, Galileo Galilei recorded the first mention of Jupiter's moons. At first thinking them to be fixed stars near the gas giant, his later observations revealed them to be orbiting Jupiter. Io, Europa, Ganymede and Callisto are now known as the Galilean moons. #HistoryOfScience

Work! Our lovely institute (@api.uva.nl) is looking for a new Institute Manager - so if you fancy trying to make sense of the mysteries of university project budgets, and herding a bunch of mostly well-behaved astronomer-cats, JOIN US!!! werkenbij.uva.nl/vacatures/in...

We're hiring! The GRAPPA center (a collaboration between the UvA's IoP and API) is looking for an assistant/associate professor in the area of gravitational-wave and multi-messenger astrophysics. Please see below for full vacancy. werkenbij.uva.nl/en/vacancies...

With warnings in place for some potential heavy snow in parts of the Midlands and Southern UK on Thursday, we may have some chances to photograph #snowflakes up close. I made a video tutorial on simple #Macro #SnowflakePhotography 4yrs ago; you can watch it here: tinyurl.com/6n6nzc4v

Happy new year! My all sky camera imaged the sky every 15 seconds and this picture shows what happened in the sky in 2025. It shows the length of the night and day with the hourglass shape, the monthly lunar cycle with the diagonal bands, the elevation of the Sun at local noon, and lots of clouds.

A year ago, I went to Copenhagen to write about the political crisis sparked by Trump over Greenland. Danes told me that the US can already do whatever it wants on the island. Their conclusion: Trump just wants the U.S. to look larger on a map www.theatlantic.com/internationa...

Belangrijk draadje over #Venezuela en de zogenaamde #neutraliteit van de @nieuws.nos.nl. Door vooral officiële bronnen te gebruiken, zijn ze juist niet neutraal maar versterken ze de macht. Een doodzonde voor een #journalistiek medium.

🚀 As we wait for the next CME — and maybe more aurora action — here’s a look at what’s racing toward Earth! ⚡️ This eruption and CME blasted out with yesterday’s X5.2 flare, complete with a powerful shock and particles hitting the cameras. Fingers crossed 🤞 and skies clear! 🌌 bit.ly/sunactivity

Looks like Bz is northwards (although decreasing) so we may be in for disappointment tonight unless the situation changes. The weather is awful here and I have a 6am flight so I am signing off for tonight 🌧️👋

We have upgraded our geomagnetic forecast today (12 November 2025) to the highest intensity level amid an ongoing solar storm. Current predictions suggest that the activity will result in potentially the largest solar storm to hit our planet in over two decades.

There is now a G5 (extreme) geomagnetic storm watch in place (Met Office), we are waiting for the third eruption to arrive although, due to uncertainty in the propagation models it is unclear whether it will arrive today or tomorrow 🌞💨🌎👀 #SpaceWeather #Aurora #StephsStormWatch
