“The Cosmos is all that is or was or ever will be , ” said Carl Sagan in Chapter 1 of Cosmos: A Personal Journey, the fantastic popular science series with which a few million people began to to become passionate about the concepts that it introduced, the history of astronomy, modern cosmology, the origin of life and the need to preserve it, or the place of our planet and our species in the Universe.
The series was continued in 2014 with Cosmos: A Time and Space Odyssey presented by astrophysicist Neil deGrasse Tyson and with Sagan’s widow as one of the executive producers and since the original Cosmos dozens of fantastic documentaries have been produced adapted to the latest discoveries and scientific theories, but the truth is that Sagan’s work continues to have a tremendous impact because of what he told and how he told it.
It is not that we are bad under the shelter of our inimitable mother Earth. Quite the opposite (if we don’t kill it, that’s another story) and it’s likely that we won’t find anything better in centuries, but the Cosmos is definitely as fascinating as the charm of the unknown. 
Astronomy websites
The Internet has been a blessing for fans and although those “meetings” with telescopes or binoculars at home are irreplaceable from time to time, the truth is that today you can enjoy the Universe by “lying down” on the sofa in the living room There are numerous online portals that bring us closer to the Cosmos and taking advantage of the unusual media interest in the arrival of Perseverance and Ingenuity on Mars, today we are going to leave you with a selection of them.
NASA.gov
The web portal of the US space agency is -of course- one of the first and great sites to visit to keep up to date with everything that is going on in space research. It has an overwhelming amount of resources for professionals and amateurs alike, that it would take you years to examine.
Space Dashboard
What is happening in space right now? An astronomy enthusiast put together a fancy website as a one-stop-shop for all the current space-related activities. A one stop shop for lots of things like:
- Live broadcast from the International Space Station.
- NASA TV, one of the best space mission broadcast webcams.
- The current position of the ISS on Earth.
- Up-to-date view of the sun’s outer atmosphere, its corona, and plasma explosions.
- How many people are in space right now and who?
- Current geomagnetic storms by K index.
- Space-based weather forecasts.
- Near-Earth objects, current and in the coming days.
- Current state of the Deep Space Network, the Deep Space network.
Exoplanet Travel Bureau
Exoplanets have always been there and the pioneers of astronomy centuries ago already assumed their existence. The problem is that they lacked the means to locate these worlds with the theoretical capacity to host life outside the Solar System. The use of the astronomical technique called “transit” (slight changes in light from the Earth’s perspective when a planet passes in front of its star) have meant a huge leap in their research, supported by specialized satellites such as Kepler and the new TESS, Similar, but with more power.
More than 4,000 exoplanets have already been located and it has only been the beginning. Telescopes like TESS, James Webb, and the giant Magellan will have the ability to study starlight passing through the atmospheres of nearby exoplanets, giving information about their composition. Later, the WFIRST telescope will be a before and after in the hunt for these worlds, since it will be able to search with more precision for water, methane, carbon dioxide and other gases that could indicate the presence of biological activity.
Sky & Telescope
It’s a paper magazine, but it has a great website full of information , interesting articles, and up-to-date space-related news. It offers beginner’s guides on all things astronomy, from stargazing to astrophotography. Another interesting feature is “This week’s sky at a glance”. Here you can study the objects that you can expect to see in the night sky if the weather conditions allow it. It provides information on easy-to-spot constellations, moon phases, and contains a planetary clock.
Space.com
Launched at the turn of the last century, it claims to be the world’s number one independent source for news on astronomy , skywatching, space exploration, commercial spaceflight, and related technologies. It really has the latest discoveries, missions, trends and futuristic ideas. You can expect a ton of information along with attractive web design and ease of navigation. Like NASA.gov, it also offers a spectacular “Picture of the Day.”
TruSat
There are almost 6,000 satellites in space, circling the world for various purposes, and Space Internet projects like Starlink are going to increase the number significantly. Satellites often collide to create space debris or are thrown off track due to galactic circumstances. TruSat is an open source online community to protect space from overpopulation. Or try.
Hubblesite.org
Last May the most famous space telescope in history celebrated its first 30 years in orbit. The joint project of the American and European space agencies has revolutionized all areas of astronomical research after observing tens of thousands of celestial bodies in detail and giving us the most beautiful images of the deep Universe. And he will continue to do so until he is relieved by James Webb, who will offer a resolution and sensitivity unprecedented in the history of cosmology.
See a Satellite Tonight
TruSat is really powerful, but it can be tricky. This page offers a simpler approach to satellite tracking, when a satellite will pass over you in the night sky and be visible to the naked eye. You turn on SAST, grant access to your current location, and within a minute you’ll get a list of some upcoming satellite passes with times noted in your local time zone.
