Answer: That thing blocking the Sun at 2:47 is... us! 🌎 SDO has entered its Earth eclipse season, a three-week period that happens twice a year. During Earth eclipse season, SDO's orbit takes it behind Earth for brief period of time, momentarily blocking the spacecraft's view.

At about 2:47 in the above video, something briefly blocks SDO’s view of the Sun. What is it? Share your guesses below – the answer will be revealed Monday, July 14 at noon ET! 🎉 More on flares & coronal mass ejections:

It’s #SunDay! This week’s (July 4 - 10) space weather report includes: · 2 M-class flares · 0 C-class flares · 32 coronal mass ejections · 0 geomagnetic storms This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity. At about 2:33, SDO performs one

From tracking plasma flows on the Sun, to detangling solar eruptions, to creating a “digital twin” of our entire neighborhood in space, NASA’s DRIVE Science Centers are on the case – and they now have new webpages! 👇 https://t.co/smnAkwVFfA https://t.co/oHI1tXrhP3

This is the view from WITHIN the Sun’s atmosphere! ☀️👀🛰️ NASA’s Parker Solar Probe just released imagery from its closest-ever flyby of the Sun, revealing details in the solar atmosphere that scientists will be studying for years. More: https://t.co/ZDyJ1ReiWC

This month, the Sun is stealing the spotlight! July’s #NASAScience calendar image showcases a spectacular solar eruption, captured in Dec. 2023 by the SUVI instrument aboard NOAA’s GOES West satellite. This SUVI 304Å image reveals plasma in the Sun’s upper chromosphere, at a

It’s #SunDay! This week’s (June 27 - July 3) space weather report includes: · 0 M-class flares · 1 C-class flare · 25 coronal mass ejections · 0 geomagnetic storms This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity. More on flares & coronal mass

It looked like a minor solar eruption — but it had a major effect on Earth. ☀️💥🌎 In April 2023, a relatively weak solar storm produced vibrant auroras visible as far south as Arizona. Now, scientists have new insights into what made this storm so impactful — and how we

Two successful launches, and that’s a wrap! 🚀🚀 The two SEED mission rockets launched from Kwajalein Atoll in the Marshall Islands on June 20 and June 28, reaching peak altitudes of 95 miles (153 kilometers) and 97 miles (157 km), respectively. Preliminary data suggest that

It’s #SunDay! This week’s (June 20-26) space weather report includes: · 2 M-class flares · 2 C-class flares · 34 coronal mass ejections · 0 geomagnetic storms This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity. More on flares & coronal mass

Thank you to the millions who watched NASA's eclipse broadcast, took time to experience the eclipse, and shared in the wonder of the Sun and our place within this amazing universe.♥️ And HUGE congrats to the @NASASun team members who made this broadcast possible! It took many

2/2 🧵 The solar wind fills space around us to create a giant "bubble" we call the heliosphere. The heliosphere’s size, shape, and dynamics are mostly still unknown — but maybe not for long! NASA’s IMAP (Interstellar Mapping and Acceleration Probe) mission, scheduled to

Four facts about the solar wind that will blow your mind: ☀️🌬️🤯 1. The solar wind has been blowing non-stop since the Sun formed about 4.6 billion years ago. ⌛ 2. It travels about 1 million miles an hour (and faster). 🏃 3. It carries about 1.5 million tons of mass away

Another daring dive by the Sun, complete! 🛰️☀️✅ On Thursday, June 19, NASA’s Parker Solar Probe completed its 24th close approach to the Sun, matching its record distance of 3.8 million miles (about 6.2 million kilometers) from the solar surface and mind-melting top speed of

It’s #SunDay! This week’s space weather report includes: · 2 X-class flares · 12 M-class flares · 38 coronal mass ejections · 1 geomagnetic storm This video from NASA’s Solar Dynamics Observatory (SDO) shows the week’s activity. The two X-class flares both erupted from the same

IMAP is now at the Astrotech Space Operations Facility near the agency's Kennedy Space Center in Florida prepping for launch later this fall. IMAP will study the heliosphere, the Sun’s magnetic bubble protecting our solar system from interstellar space. More about IMAP:

So fresh and so clean, clean 🧼🫧 Inside the clean room at the Johns Hopkins Applied Physics Lab, NASA’s IMAP (Interstellar Mapping and Acceleration Probe) got its 10 instruments integrated into the spacecraft. 👇
