In the photo from the space station, the comet is captured just above Earth’s horizon, which is illuminated by a bright light — also known as airglow — that occurs in the planet’s upper atmosphere when atoms and molecules emit light after being excited by sunlight.

I pick out North America’s celestial highlights for the week ahead (which also apply to mid-northern latitudes in the northern hemisphere).

Astronomer Dean Regas gives us the lowdown on the best things to look out for this winter, from a “planet parade” to the ATLAS comet.

On Monday night you may have a chance to witness the moon obscuring the Red Planet at its brightest, as well as a comet’s closest approach to the sun.

Four of the planets, Venus, Mars, Jupiter and Saturn will be visible to the naked eye ... To top it all off, towards the end of the week there should be a comet that can be seen with the naked eye in the south-west, he said. The view of the comet was ...

Venus, Saturn, Jupiter and Mars will appear to line up and be bright enough to see with the naked eye in the first few hours after dark. This weekend, Venus and Saturn get especially cozy.

Twenty years ago today, I watched TV coverage of a probe descending toward the surface of Titan, a moon of Saturn, while outside my home in Utah snow dusted a rocky mountain outcrop I’d ...

Six planets grace the sky this month in what’s known as a planetary parade, and most can be seen with the naked eye. These planetary hangouts happen when several planets appear to line up in the night sky at once.

Mars in 2024 was the site of the sad end of a machine that lived far beyond expectations. On January 18, NASA's Ingenuity Mars helicopter flew for the last time. Given that on landing its rotors broke off, that's a pretty definitive conclusion.

What's truly unique is seeing four or five bright planets at once, which doesn't happen annually. During the planet parade, six planets will align with four of them being easily visible to the naked eye.

The planetary parade includes Venus, Mars, Jupiter, Saturn, Uranus and Neptune during January and early February.
