Riding the edge of darkness, to beyond the horizon.
Our atmosphere acts as a lens, distorting the sun as it crosses the horizon.

and yet some people still dont think there’s life on other planets
Not strictly true - this’ll only happen if the comet survives its close encounter with the Sun with enough volatiles intact to make a nice tail by the time it’s close to Earth, which isn’t guaranteed.
If it does survive, though, this is going to be the comet of the century, outshining the full moon at night and possibly visible during the day.
Neptune hasn’t completed an orbit since it was discovered
Yes it has.
Neptune was discovered on September 23, 1846. It has an orbital period of 164 years and 288 days. It completed its first orbit, since discovery, on July 11, 2011.
did we just find a habitable super-Earth?! Yup!
Super-Earth Discovered in Star’s Habitable Zone
Scientists added three new planets to three discovered in 2008 orbiting an orange star called HD 40307, which is roughly three-quarters as massive as the sun and located about 42 light-years away in the constellation Pictor.
Of particular interest is the outermost planet, which is believed to fly around its parent star over 320 days, a distance that places it within HD 40307’s so-called “habitable zone.”
“All we know at this point is that it has a minimum mass of about 7.1 Earth-masses. We have no explicit follow-up planned, thought the HARPS team is probably still gathering more data, and may in the future be able to confirm these results, and perhaps add even more planets to the brood,” astronomer Steven Vogt, with the University of California’s Lick Observatory, wrote in an email to Discovery News.
Based on our experience with other star systems this newly discovered planet is likely made of rock and may contain water. It receives 62 percent of the radiation from its star that Earth receives from the sun, but Earth is relatively near to the leading edge of the habitable zone.
Voyager 1 Detects Weirdness at Solar System Edge
She may be old, but you can’t keep a good probe down.
Voyager 1 is the most distant man-made object and is thought to have recently escaped the sun’s sphere of influence. The probe, launched 35 years ago, is therefore mankind’s first interstellar vehicle careening into the vast expanse of space between the stars.
Every minute we learn more about the unknown…
Valery Bykovsky, Valentina Tereshkova and Yuri Gagarin (June 1965). Gagarin was the first man in space, Tereshkova the first woman, and Bykovsky holds the record for longest solo space flight.
Those are three world heroes right there.
