Comet C/2021 A1 (aka Leonard) was discovered last year in January when it was zooming at 5 AU from the Sun. Having an orbital period of over 80,000 years, Leonard also has a nucleus that measures about 1km across. In ...
The closest solar system to ours is located about 4.3 light-years away from Earth. It’s known as Alpha Centauri, and it’s the place where at least three planets revolve around the Proxima Centauri host star. In other words, finding interstellar ...
The Universe is not acting very friendly toward us lately, and unfortunately, we have to take into account another asteroid of imposing size that will approach our planet soon enough. 2022 RW is the ‘wiseguy’ in question, and it shall ...
The enormous diversity of life that’s teeming on Earth today (about 8.7 million species, including plants) will be long gone in a few billion years if nothing miraculous and unexpected happens. Let’s just say that the weather will become bad… ...
We don’t know yet how, when, or who will be the lucky passengers, but it seems inevitable that humans will land on Mars. Apart from being a highly-ambitious goal, we can also see it as an important step in exploring ...
Getting to Mars is obviously no child’s play. But once astronomers figure out completely how to land there, they’ll have to grow some plants on the Martian soil as well. While the Red Planet doesn’t have any plants now, as ...
All four giant planets from our Solar System (Saturn, Jupiter, Uranus, and Neptune) have some level of ‘rings,’ meaning debris from comets, asteroids, shattered moons, etc. If you’re at least a bit interested in astronomy, you know very well that ...
Let’s admit it: despite the huge amount of knowledge that astronomers have about the Universe, sending astronauts to the nearest planet to us is still difficult. At its closest approach, Mars is still tremendously farther away from Earth than the ...
It seems that Earth remains a not-so-safe place, as many of us like to believe. After the 2016 CZ31 and 2013 CU83 asteroids passed by our planet last weekend at great speed, it’s now time for another huge space rock ...
Sending the first astronauts to Mars is hard enough, as space agencies still struggle to find out exactly how to do it. But perhaps bringing rock samples from the Red Planet in order to study them up-close on Earth will ...
