That's a good question here's the latest study by Lior Shamir, a K-State computational astronomer and computer scientist:

An analysis of > 200000 spiral galaxies has revealed that the early universe could have been spinning.

A spiral galaxy is a unique astronomical object because its visual appearance depends on the observer's perspective. For instance, a spiral galaxy that spins clockwise when observed from Earth, would seem to spin counterclockwise when the observer is located in the opposite side of the galaxy. If Universe has no particular structure — as previous astronomers have predicted — the number of galaxies that spin clockwise would be roughly equal to the number of galaxies that spin counterclockwise. Shamir used data from modern telescopes to show that this is not the case.

When comparing the number of galaxies with different spin directions, the number of galaxies that spin clockwise is not equal to the number of galaxies that spin counterclockwise. The difference is small, just over 2%, but with the high number of galaxies, there is a probability of less than 1 to 4 billion to have such asymmetry by chance, according to Shamir's research.

Hubble near-infrared and near-ultra-violet photos of NGC 6302 & 7027

Astronomers have discovered evidence for thousands of stellar mass black holes (which typically weigh between 5 to 30 times the mass of our Sun) located near the center of our Milky Way.

The galaxy known as NGC 5907 [Knife Edge Galaxy] stretches wide across this image. The Knife Edge Galaxy is ~ 50 million ly from Earth, lying in the northern constellation of Draco.

Image of star cluster G286.21+0.17, caught in the act of formation. This is a multiwavelength mosaic of more than 750 ALMA radio images, and 9 Hubble infrared images. ALMA shows molecular clouds (purple) and Hubble shows stars and glowing dust (yellow and red).

Io transit

This image from NASA’s Juno spacecraft captures several storms in Jupiter’s southern hemisphere (Figure A). Some of these storms, including the Great Red Spot at upper left, have been churning in the planet’s atmosphere for many years, but when Juno obtained this view of Jupiter, the smaller, oval-shaped feature at the center of the image was brand new.

The new feature was discovered by amateur astronomer Clyde Foster of Centurion, South Africa. The feature is a plume of cloud material erupting above the upper cloud layers of the Jovian atmosphere. These powerful convective "outbreaks" occasionally erupt in this latitude band, known as the South Temperate Belt (JunoCam observed another outbreak at this latitude back on Feb. 7, 2018).

After more than a year in a clay-rich region, NASA's Curiosity Mars rover is making a mile-long journey around some deep sand so that it can explore higher up Mount Sharp.

The barred spiral galaxy known as NGC 4907 shows its starry face from 270 million ly away. Shining brightly below the galaxy is a star that is actually within our own Milky Way galaxy. This star appears much brighter than the billions of stars in NGC 4907 as it's 100000 times closer, residing only 2500 ly away.

This long-exposure photograph captures a starry sky above the Earth's atmospheric glow as the ISS orbited above the Indian Ocean about halfway between South Africa and Australia.

Many colorful stars are packed close together in this image of the globular cluster NGC 1805, taken by the NASA/ESA Hubble Space Telescope. This tight grouping of thousands of stars is located near the edge of the Large Magellanic Cloud, a satellite galaxy of our own Milky Way. The stars orbit closely to one another, like bees swarming around a hive. In the dense center of one of these clusters, stars are 100 to 1000 times closer together than the nearest stars are to our Sun, making planetary systems around them unlikely.

Scientists precisely measure total amount of matter in the Universe

Matter makes up 31.5±1.3% of the total amount of matter and energy in the Universe, with the remainder consisting of dark energy.

“To put that amount of matter in context, if all the matter in the Universe were spread out evenly across space, it would correspond to an average mass density equal to only about six hydrogen atoms per cubic meter,” said first author Mohamed Abdullah, a graduate student in the UCR Department of Physics and Astronomy. “However, since we know 80% of matter is actually dark matter, in reality, most of this matter consists not of hydrogen atoms but rather of a type of matter which cosmologists don’t yet understand.”
