𝗪𝗢𝗪!! Astronauts just witnessed something NO human has ever seen before 🤯🌑☀️

During the Artemis II lunar flyby on April 6, the crew aboard Orion captured a total solar eclipse FROM DEEP SPACE — something no human eyes have ever witnessed before. And it wasn't a quick flash of totality like we get on Earth. From their vantage point near the Moon, the Moon was close enough to block the Sun for nearly 54 MINUTES of totality. On Earth you get maybe 7 minutes on the best day ever. This was almost an hour! Let that sink in 🤯⏱️☀️🌑

Three incredible perspectives tell the story:
🔭 A close-up showing the Sun's corona glowing around the Moon's edge — with Venus photobombing on the left! ✨ You can even see Mare Crisium on the lunar surface, lit by Earthshine — light bouncing off the Earth and illuminating the Moon's nearside even during totality 🌍➡️🌑

🌑 The full eclipse with a mysterious glowing halo wrapped around the dark lunar disk that scientists are already investigating — corona? Zodiacal light? Both? 🔬🤔 Plus stars popping out that you'd never normally see when imaging the Moon, but with the surface in darkness they appeared clearly. Hidden stars revealed! ⭐👀

☀️🌅 The Sun peeking back out after nearly an hour of darkness — the reemerging sunlight creating a sharp contrast against the Moon's silhouette and revealing lunar topography along the limb, with mountains casting shadows you don't normally get to see. What a way to end the show! 🏔️✨

These aren't just beautiful photos — they're valuable solar science data from a perspective humanity has never had before 🔬🌟

This is what happens when you send humans to deep space with cameras and curiosity 📸

Humanity went back to deep space and brought home views we've literally never had before. What a time to be alive 🚀✨🙌

☀️🌍🌕 WHERE CAN YOU SEE THE TOTAL LUNAR ECLIPSE?

Watch the Shadow Move Across the Globe.

On March 3, 2026, the Moon slides into Earth's shadow, and this animation shows exactly who gets a front-row seat and who misses out.

Watch the shaded region sweep westward across the globe. If you're inside that region, you can see the eclipse. If you're on the edge? That's where it gets interesting. 👀

🌅 Eastern edge (right side): The Moon is setting as the eclipse happens. Observers here see the Moon sink below the horizon mid-eclipse. Imagine watching a Blood Moon melt into the sunrise. Dramatic, but you won't see the whole show.

🌄 Western edge (left side): The Moon is rising already in eclipse. You'll step outside to see a red Moon climbing above the horizon, no waiting required.

🎯 The contour lines on the map mark the boundaries at each "contact time," the moments when the Moon enters or exits the two parts of Earth's shadow:
→ Penumbra: the outer, lighter shadow where the Sun is only partially blocked. The dimming is subtle at first.
→ Umbra: the dark inner shadow where the Sun is completely hidden. This is where the magic happens and the Moon turns red. 🔴

If you're on a contour line, that contact happens right at your moonrise or moonset. If you're well inside the region, you get the full show from start to finish.

🌏 Best seats in the house:
→ Japan, Korea, eastern China, Australia, New Zealand, Hawaii, Alaska
→ Western US & Canada see the full event in the pre-dawn sky
→ Eastern US & Canada catch totality as the Moon sets at dawn
→ Europe & Africa, sorry, not this time 😔

This is the LAST total lunar eclipse until December 31, 2028, nearly three years away. If you're in the visibility zone, don't miss it.

[Dr. C. Alex Young @TheSunToday]

🌔 🌏 🌞 THIS IS IT. The Last Total Lunar Eclipse for Nearly THREE YEARS.
On the night of March 2–3, 2026, the Moon will drift into Earth's shadow and turn a deep, haunting red. It's called a Blood Moon and after this one, you won't see another total lunar eclipse until December 31, 2028. That's a 1,034-day wait. So yeah… don't sleep through this one. 😅

Here's why this eclipse is special:

🔴 Nearly 59 minutes of totality. That's almost a full hour of Blood Moon hanging in the sky. Plenty of time to step outside, grab a drink, take photos, have an existential moment, and still catch the best part.

🎨 A two-toned Moon. This isn't your average red Moon, the southern half will glow a deep crimson while the northern limb shines coppery-orange. The color gradient across the lunar disk will be stunning for photographers and stargazers alike.

🔭 Bonus: The Moon will occult a GALAXY. During totality, the darkened Moon passes in front of galaxy NGC 3423. Astrophotographers, this is your moment. A deep-sky occultation during a total lunar eclipse is absurdly rare.

🌏 Who can see it?
→ 🇯🇵🇰🇷🇦🇺🇳🇿 Best views: Japan, Korea, Australia, New Zealand, Hawaii, Alaska, western US & Canada

→ 🌅 Moonrise eclipse: Australia & NZ will see the Moon rise already red, dramatic!

→ 🌄 Pre-dawn views: Eastern North America can catch totality as the Moon sets at sunrise

→ ❌ Sorry Europe & Africa, this one misses you entirely
→ 📺 Everyone else: Livestreams!

⏰ Key times (UTC):
→ Partial eclipse begins: 09:50 UTC
→ Totality begins: 11:04 UTC
→ Greatest eclipse: 11:34 UTC
→ Totality ends: 12:03 UTC

👁️ No special glasses needed. Unlike a solar eclipse, a lunar eclipse is 100% safe to watch with your naked eyes. Binoculars and telescopes make it even better, but all you really need is a clear sky and a willingness to look up.

🏁 End of an era. This completes an incredible streak of THREE consecutive total lunar eclipses in just one year:
🌕 March 2025 ✓
🌕 September 2025 ✓
🌕 March 2026 ← You are here!

After tonight? The Moon goes into hiding. The next total lunar eclipse won't arrive until New Year's Eve 2028. Make this one count. 🥂🌑

🔥💍 TOMORROW MORNING: A "Ring of Fire" Solar Eclipse And It's One of the Loneliest Eclipses in Modern History!

On Monday, February 17, 2026, the Moon will slide in front of the Sun and create a stunning golden ring of fire in the sky. There's just one catch: the only place on Earth to see it is Antarctica. 🐧🇦🇶

Here's what makes this eclipse so extraordinary:
🧊 The most remote eclipse imaginable. The annular path crosses the frozen interior of Antarctica, where only a handful of researchers at stations like Concordia and Mirny will witness the ring of fire in person. No tourist trips, no roadside viewing, just ice, silence, and the cosmos.

💍 Up to 2 minutes 20 seconds of annularity. The Moon will block 92.7% of the Sun, leaving a brilliant golden ring glowing against the Antarctic sky. Because it's an annular eclipse (not total), the Sun is NEVER fully covered, which means it is NEVER safe to look without proper eye protection!

🌍 Partial views for parts of the Southern Hemisphere. If you're in southern South Africa, Madagascar, Mauritius, Réunion, southern Chile, or Tierra del Fuego, you'll see the Moon take a bite out of the Sun. Check https://t.co/L4yt9BLqNC for your local times.

📺 For the rest of us: Watch it LIVE online! Livestreams from https://t.co/L4yt9BLqNC and other broadcasters will bring Antarctica's ring of fire right to your screen. Links are in our full guide.

🌑🌕 And this is just the beginning! This eclipse kicks off a FOUR-eclipse year:
→ Feb 17: Annular Solar Eclipse (tomorrow! 💍)
→ Mar 3: Total Lunar Eclipse, the LAST one until late 2028! 🔴
→ Aug 12: Total Solar Eclipse over Iceland & Spain ☀️🌑
→ Aug 28: Partial Lunar Eclipse 🌗

⚠️ EYE SAFETY REMINDER: An annular eclipse is NEVER safe to look at without certified solar eclipse glasses or a solar filter. Unlike a total eclipse, there is no moment when you can look with unprotected eyes. Protect your vision!

A great summary of the current storm status!

[☀️ Sara Housseal ☀️ @SNHWx]

SOLAR STORM ONGOING: Based on the strong decrease in both low and high energy protons, we are now in a more stable, core structure of the CME. The magnetic field is currently pinned in the +Bz (north) direction, which is generally not ideal for aurora, but due to the overall strength of the CME, secondary components are able to maintain some degree of life within the auroral currents. Long term, this method can prevent aurora from stretching as far south and being as active/vibrant.

There is still an opportunity for the Bz component to flip southward based on different magnetic configuration scenarios. So unfortunately, more waiting is still required.

[Vincent Ledvina @Vincent_Ledvina]

I'll be going LIVE on WeatherNation in about 15 minute at 3:40 pm MST / 1:40 pm AKST to talk about this CME and what may be in store for North America tonight...

[Dr. C. Alex Young @TheSunToday]

What we saw earlier was the shock front. Now it appears the main body of the CME is arriving at Earth. 🌍💥

The catch: the Bz is strongly northward right now. ⬆️
If it stays north, storm impacts will be limited. If it turns south and holds, the storm could ramp up quickly.

Now we watch and wait. 👀

[Dr. C. Alex Young @TheSunToday]

🌟 Update for Aurora Watchers — the storm has arrived! 🌟

The CME has officially impacted Earth’s magnetosphere at approximately 2:38 a.m. Eastern Time, and it didn’t arrive quietly. Earth’s magnetic field is now rattling hard, with conditions reaching G4 (Severe) geomagnetic storm levels. ⚠️🌍

This is a strong event, and it means auroras may be visible much farther south than usual, depending on local conditions and how the storm evolves.

🌌 If it’s dark where you are — happy aurora hunting!
👀✨ Keep watching the skies, especially toward the northern horizon.

🛰️ We’ll continue to monitor the storm closely and share updates as it unfolds.
