Euclid is a telescope sent in space but close to Earth by the European Space Agency (ESA) and he sent back images from the universe around us. In just one week of observations, with one scan of each region so far, Euclid already spotted 26 million galaxies. The farthest of those are up to 10.5 billion light-years away.

Most probably we are not alone in the Universe but how close to find out we are I can only wonder. The number of galaxy if high, each galaxy have a high number of stars and many of them - maybe most of them - has at least a planet orbiting it. The planet may have one or more satellites. Most planets and most satellites could host life so the chances to be alone are pretty small, probably one person has more chances to win the big lottery prize each draw time after time for an entire year with only one ticket for each draw than humans being alone in our galaxy alone.

Moon, rings, asteroids and comets passing by or hitting the Earth like balls heating their targets - planets have them all. We don't have now a ring around the planet but it seems that our planet had something like this long time ago -millions of years - and Scishow team is saying something about it and its effects.

NASA's Parker Solar Probe was sent to study the Sun and now it is making history by flying closer to the sun than any human made object in history. The solar probe was due to zip past the sun for a flyby on Christmas Eve, travelling at more than 430.000 miles per hour.

The galaxy is big and interesting enough to keep discovering many new things, and one of thing things is a new planet discovered orbiting closest single star to our Sun: using ESO’s Very Large Telescope, astronomers have discovered a planet orbiting Barnard’s star, the closest single star to our Sun (Alpha Centaury is a binary star system - a system with two stars).

Short answer, yes, there can be life on Jupiter's moon and NASA's Europa Clipper spacecraft will scour Europa for the ingredients for life even if we cen be alone in the solar system, alone in the galaxy or even alone in the univers considering life in general and intelligent life in special.

The light need a long time to travel between stars but there are many things in the galaxy and the universe that happen in a quite short time so we need tools to see them in real time when the light reach our planet. The New Robotic Telescope (NRT) is an international and collaborative project to build the world’s largest robotic telescope; the first responder to explosive and rapidly fading sources in the night sky.

A NASA spacecraft is ready to set sail for Jupiter and its moon Europa. The craft named Europa Clipper will peer beneath Europa's icy crust and determine whether conditions there could support life.

Some people are having too much free time on their hands and they are getting on Youtube videos like this one, with our solar system reimagined. The have enoughh data to do that because over the centuries many planets have been predicted to be real, but they were never discovered.

Oumuamua, the first discovered interstellar object, accelerated faster than it should have and that made may people puzzled because the normal asteroids and comets do accelerate only under the influence of external forces like being pushed or hits or coming in places too closed to planets and stars and being influenced by the space curvature (their gravity). So, how did it accelerated so fast? The astrophysicist Neil deGrasse Tyson and comic co-host Chuck Nice dive in the StarTalk episode into the mysteries of the newest objects in the solar system: “dark comets” and interstellar objects with astrophysicist Darryl Seligman.

A group of skywatchers thanked their lucky stars for being among those who were able to witness the “ring of fire” eclipse of the sun on Wednesday (yestedaym 2nd of October 2024) and Associated Press posted their images. The annular solar October 2024 eclipse was visible over Easter Island and the tips of Argentina and Chile.

The info should be in the World news category but astronomy is involved and it's more important to be here. It's not astronomy discovery yet, but it can became in time a discovery if the Argentinians are good enough and they are watching the sky often enough.

The infrared astronomy has become something important, especially after the James Webb telescope had some wonderfull results, and there are several ways to see using infrared what's happening in galaxy and universe.

It's still very far, at least decades, or even centuries, until we will be able to colonize another plantes, but our interest about them are still very high. Two days ago, April 18, 2013, this image was posted on Facebook, probably taken from NASA in some way, with information about 3 new planets that could host life... Scientists announced this Thursday the discovery of three planets that are some of the best candidates so far for habitable worlds outside our own solar system, and they're very far away.

Sky glow is the illumination of the night sky (partially or completely). Its most common cause is the artificial light of the cities which accumulates into a vast glow that can be seen from many kilometers away in any direction. Sky glow from the artificial lights is common througho
