‘What is that ?’ Spotted super bright object moving towards the sun

A fascinating video has captured Venus moving around the solar system as it’s caught in the sun’s glare.

On Thursday evening, solar expert Keith Strong posted a video of a coronagraph on Twitter that showed a glowing light on the right side of the clip.

A coronagraph is a scientific instrument designed to block direct sunlight, so astronomers can see its corona, the hot outer layer of the sun’s atmosphere.

As such, coronagraph videos and images have a black circle in the middle that covers the sun, while the ghostly white light around the circle is the energy given off by the sun.

Coronagraph images are useful for spotting all kinds of solar activity, from solar flares to coronal mass ejections. Additionally, they can also be used to spot non-solar objects.

“What the hell is that?”, Strong tweeted, next to the next coronagraph clip. “There is a bright object on the right edge of the frame that appears, that is, moving in the opposite direction to the stars.”

Like the sun, the object also seemed to emit a ghostly glow.

Strongly stated that the object was actually the planet Venus, which is currently on the far side of Earth’s sun.

“Coronographs are designed to observe the very weak solar corona,” said Martin Archer, space physicist and science communicator. Pleasemynews. “Planets, on the other hand, are very bright and tend to saturate in detectors. For this reason, they usually end up looking much larger than they really are and are often surrounded by lens flare effects.

“This is likely what causes the bright light patterns around Venus in the video, these effects being particularly strong because Venus is on the opposite side of the sun to the brightly lit Earth.”

Mathew Owens, professor of space physics at the University of Reading in the UK, echoed this point.

“So while Venus is small enough to be essentially a single pixel in the camera, it’s so bright that it ‘bleeds’ into surrounding pixels,” he said. Pleasemynews. “This usually happens when planets and comets wander through the coronagraph’s field of view.

“It’s kind of like wearing night vision goggles and looking at car headlights.”

NASA’s Stereo Science Center website shows a sort of bird’s-eye view of the positions of the planets in the inner solar system right now. This shows how Venus is indeed on the opposite side of the sun to Earth, which means we see it bathed in sunlight.
