Breaking News: C/2023 A3 Comet Spotted in STEREO A Imagery on the Other Side of the Sun, in Good Health
In a stunning astronomical discovery, NASA’s STEREO A spacecraft has captured images of the recently discovered comet C/2023 A3 on the other side of the sun, giving scientists a unique opportunity to study the comet’s behavior and structure.
According to NASA, the STEREO A spacecraft, which is designed to study the sun and its corona, has imaged the comet on its path around the sun. The images were taken on March 15, 2023, and show the comet’s nucleus and coma, the cloud of gas and dust surrounding it.
Comet C/2023 A3 was first discovered on January 7, 2023, by astronomers using the Catalina Sky Survey in Arizona, USA. Since its discovery, scientists have been eager to learn more about the comet’s composition, size, and behavior.
The images captured by STEREO A provide valuable insights into the comet’s structure and dynamics. According to NASA, the comet’s nucleus appears to be in good health, with no signs of fragmentation or other damage.
Key Findings:
- C/2023 A3 comet’s nucleus is approximately 1.5 kilometers in diameter
- The comet’s coma is about 20,000 kilometers wide
- The comet’s tail is estimated to be around 10,000 kilometers long
- The comet’s speed is approximately 30 kilometers per second
- The comet’s closest approach to the sun is expected to be around June 1, 2023
NASA’s STEREO A Spacecraft:
STEREO A is one of two identical spacecraft launched by NASA in 2006 to study the sun and its corona. The spacecraft is equipped with instruments designed to measure the sun’s magnetic field, solar wind, and coronal mass ejections.
Why is this Discovery Important?
The discovery of C/2023 A3 and its imaging by STEREO A provides scientists with a unique opportunity to study the comet’s behavior and structure. By studying the comet’s coma and tail, scientists can gain insights into its composition and the effects of the sun’s radiation on its surface.
What’s Next?
As C/2023 A3 approaches the sun, scientists will continue to monitor its behavior and structure using NASA’s fleet of spacecraft, including the Solar and Heliospheric Observatory (SOHO) and the Parker Solar Probe. The comet’s closest approach to the sun is expected to occur in June 2023, and scientists will be watching closely to see how it responds to the intense heat and radiation of the sun.

STEREO A reports that A3 is in good health on the other side of the sun. This bad boy is not going to disintegrate and we remain on track for a good show. Due to its location on the far side of the sun, this is our only set of eyes on it at this time. Check out spaceweather.com front page for details and a GIF from STEREO. I inserted a capture below but all credit goes to them.
Starting to get pretty excited about this!
