The NASA/ESA Hubble Space Telescope provided astronomers with their best look yet at an interstellar visitor — Comet 2I/Borisov — which is believed to have arrived here from another planetary system elsewhere in our galaxy.

At age ten, Vera Rubin was fascinated by the stars, as she watched the night sky revolve from her north-facing bedroom in Washington D.C. Although her father was dubious about the career opportunities in astronomy, he supported her interest by helping her build her own telescope and going with her to amateur astronomers’ meetings. She got a scholarship to the prestigious women’s college Vassar, where she graduated as the only astronomy major in 1948.

For the first time ever, we have discovered planets beyond our own Milky Way galaxy.
We have long been unable to find exoplanets outside the solar system beyond the confines of the Milky Way. After all, our galaxy is a warped disc about a hundred thousand light-years across and a thousand light-years thick, so it's incredibly difficult to see beyond that.

The Sun’s fiery hot sphere produces a variety of special features. Maybe the most intriguing is a so called solar prominence.
A solar prominence is a large, bright feature extending outward from the Sun's surface. Prominences are anchored to the Sun's surface in the photosphere, and extend outwards into the Sun's hot outer atmosphere, called the corona.

On June 16, 2018 there was an unusual flash in the sky which puzzled astronomers around the world. The flash event was called AT2018cow and has been nicknamed “The Cow,” and scientists have been debating its source since then.

Here is the light curve since 2010 for R Leonis.

This Mira type variable has an average period of approx 310 days, so maxima occur nearly two months earlier each year.
With R Leo being located close to the ecliptic, there is a gap in the light curve each summer when Leo is in conjunction with the Sun.
