Here it is: the third installment of the very best science and nature photos from 2019. We've got everything here: space, nature, animals and the Earth. Continual improvements in technology and photography mean that we can see the world and beyond in more detail, and have more knowledge about it all, than ever before. See part I here and part II here. Can't get enough of this brain food? Check out these fifteen strange galaxies.
There are quite a few seals in Antarctica wearing these satellite tags, which are helping scientists collect data about water conditions. Cute little helpers!
Scientists recently discovered an anomaly of heavy matter below the biggest crater in the universe, which happens to be on our Moon's South pole. The anomaly is thought to be the remains of a 4 billion year old asteroid.
This magical photograph is capturing a sparkling nebula, taken by Steven Mohr from Carapooee, Victoria, Australia. The nebula is 1.500 light years away from Earth in the Orion constellation.
On 16 March, April the giraffe had her fifth calf, called Azizi. She's now going on birth control (yep, animals can do that!).
The Raikoke volcano from above on 2 June, as seen from the International Space Station.
This image shows the Moon's shadow passing south of Hurricane Barbara during the total solar eclipse on 2 July.
A man inspects a crack in the Earth near Ridgecrest in the Mojave Desert after a 6.4 magnitude earthquake shook California on 4 July. It was the biggest earthquake in 20 years.
This is the Natural Bridges National Monument in southeastern Utah. The three bridges have Hopi names: "Owachomo" meaning "rock mounts" (shown here); "Sipapu" meaning "place of emergence;" and "Kachina" meaning "dancer." This park is the first designated dark sky park.
In 2019, astronomers detected a radio halo surrounding a galaxy for the first time ever. This photo shows galaxy NGC 4565, and it's about 38.8 million light years away from us. The radio ring, which appears in the center of the galaxy, is the result of massive supernovas sending high-energy particles out toward the edges of the galaxy.
This photo isn't edited: this is an image taken by Uma Gopalakrishnan from North Carolina, who happened to capture this incredible phenomenon on camera. A cloud shadows half of the sky, making it appear like day and night are colliding.
This adorable creature is a piglet squid. Marine scientists found this little guy in the central Pacific Ocean near Palmyra Atoll in July, and at first they were baffled by the little fella, having never seen one before. Isn't it cute?
This otherworldly photo shows the International Space Station floating across the Sun (between 11 and 12 o'clock). It was captured by photographer Rainee Colacurcio with a special telescope for observing the Sun.
These cute creatures are American crocodiles. Many have been found to be thriving in canals in southern Florida. Scientists implanted 73 hatchlings with microchips so they can keep track of the crocodiles.
