Poor Capricornus. The early Greek stargazers labeled it as a Sea Goat, but no amount of squinting - or even imagining - can help you see a Goat in this part of the sky. In 2020, Jupiter and Saturn come to the rescue!
Earth will pass between Mars and the sun in October 2020, and the distance between our 2 worlds is now relatively small. And so Mars is very bright now! Thanks to all in the EarthSky Community who captured Mars near the moon this past weekend.
A new map created by a Reddit user - based on what we know about the highs and lows on Venus' surface - shows what this neighboring, cloud-shrouded, blazing hot planet might look like with oceans. Wow!
Cracks in Europa's surface indicate the moon's outer ice shell has shifted by as much as 70 degrees over the past several million years. It's the kind of movement you'd expect from a planetary crust floating on a subsurface ocean.
These next several nights - September 4, 5 and 6, 2020 - let the moon introduce you to the red planet Mars. Next month, in October 2020, Mars will supplant Jupiter as the sky's 4th-brightest heavenly body.
The researchers called their new analytical technique "a milestone in SETI." One researcher commented: "We now know that fewer than one in 1,600 stars closer than about 330 light years host transmitters just a few times more powerful than the strongest radar we have here on Earth."
The orbit of asteroid 2011 ES4 is still not entirely known. Our knowledge of it might improve sometime today - or early tomorrow - if it is "recovered" by astronomers. It's expected to pass within the moon's orbit, possibly as close as 0.19 lunar distances.
