There has been no shortage of breathtaking space photos shared in 2021, from both the legendary, Earth-orbiting Hubble Space Telescope and from extraterrestrial missions. Take a minute to relax and take in the beauty of outer space and remember that, amid all these expressions of energy and matter swirling, expanding, and colliding across the universe, we’re right here in the middle of it all. That’s pretty cool.
These are the most stunning photos of space of 2021 (so far):
A newborn star’s outburst

This captivating picture focuses on a newly formed protostar violently ejecting long streams of matter at incredible speeds, a rare phenomenon known as a Herbig-Haro object. As the matter hits surrounding gas, the collisions erupt in bright, colorful bursts. The star itself isn’t visible amidst this flurry captured by Hubble, but its presence is felt in the gap between the diagonal bursts.
A Martian immersion
NASA’s Perseverance rover captured a panorama of the Octavia E. Butler Landing site on Mars, providing us earthlings with an immersive, 360-degree view of its new Martian home as of Feb. 18. The sweeping vista of the 28-mile-wide Jezero Crater formed by a meteorite impact lets us imagine what it’s like to be right there along for the mission. Within Jezero Crater is evidence of an ancient river delta where water once ran on the surface of Mars, and Perseverance will be collecting data in the area as well as preparing samples of soil to be picked up and returned to Earth in a future mission.
A black hole’s magnetic field
The Event Horizon Telescope (EHT) released a new view of the Messier 87 black hole in polarized light.

At the center of the Messier 87 galaxy some 55 million light year away lies a black hole. In 2019, a collection of scientists that observed the object using an array of telescopes around the globe released the first-ever image of a black hole, which depicts the light surrounding its dark center, almost like a blurry lava donut. In 2021, we got a new polarized image of the black hole created using more data compiled by the telescopes, which may look similar to the original image but gives new insight into this behemoth. The new lines seen in the ring of light show the gravitational field of this supermassive object, which in turn shows how it affects the material around it.
Evil eye galaxy
This galaxy is often referred to as the “Black Eye,” or “Evil Eye,” galaxy because of the dark band of dust that sweeps across one side of its bright nucleus.

NGC4826, also known as the Evil Eye or Black Eye galaxy, is a spiral galaxy about 17 million light years away from Earth. The gas in the inner part of the galaxy rotates in one direction, while the gas further away from the center rotates in the opposite direction, an odd trait for a galaxy. One theory suggests this is because Evil Eye is the result of two galaxies colliding. The dark, almost fluffy-looking gas that wraps its way throughout gives it an almost ominous appearance; hence, the name.
Thermal images of Martian dunes
The chilly dunes of Mars are given a colorful embellishment based on thermal data.

The dry and dusty surface of Mars has been shaped into dunes in many locations around the planet, resembling those seen in sandy locations on our own planet. The Mars Odyssey orbiter has been gathering temperature data across the Martian surface for nearly 20 years, and temperatures are pretty low around Mars’s north pole. The image above shows about 19 square miles of Martian dunes with color enhancements indicating thermal data. The orange peaks signify warmer temperatures and the flatter areas are colored blue to show they’re colder. NASA did not specify the temperatures measured in the image, but we know the average Mars temperature is -81 degrees Fahrenheit and near the poles it can dip down to as low as -195 F. It’s not exactly how we’d see Mars with our own naked eyes, but it’s a fascinating new way to observe a relatively desolate planet.
Storms of Jupiter
This image of Jupiter shows amazing detail of its stormy, cloudy atmosphere.

NASA’s Juno spacecraft has been orbiting Jupiter since 2016, collecting all kinds of data to demystify the big, billowy gas giant and help scientists understand more about our solar system. In this image taken by Juno and color enhanced by citizen scientist Tanya Oleksuik, we see an impressively vivid collection of circular, swirling storms amidst its gaseous bands that circulate south of its famous red spot. The turbulent atmosphere is downright mesmerizing. Jupiter’s atmosphere is made up mostly of hydrogen and helium and it doesn’t have a solid surface like Earth, so storms are constantly occurring. It’s biggest storm, the red spot, is twice the size of Earth and has raged for about 100 years.
Venus, Earth’s closest neighbor, gets a dramatic photoshoot.

NASA’s Parker Solar Probe is on a hellish mission to the sun where it will gather as much data as it can before its fiery demise, and on the way it passed by Venus. This image, taken by the probe as it zoomed by in July 2020, gives an almost eerie look at one of our closest planetary neighbors. The dark area on Venus is part of the Aphrodite Terra highlands region, which extends around two-thirds of the planet and is home to plenty of flowing lava. The streaks of light that give the image so much life may be particles of dust lit by the sun, or maybe dust that collided with the probe. Stars dotting the background are just icing on the cake.
Perseverance touching down
Perseverance’s last moment before safely reaching its destination.

It’s a big year for Mars, in case you hadn’t already noticed. This image captures the moment just before NASA’s Perseverance touched the surface of the red planet where it will live out its days indefinitely. The dramatic photo was taken by the rover’s jetpack-like lander as it hovered 60 feet above the surface, lowering the rover softly to the ground. The rover traveled with the lander for almost 300 million miles to Mars, the pair entering Mars’ atmosphere at a blistering 1,000 miles per hour with not much more than a parachute to slow it down. Yes, the picture is a unique look at an extraterrestrial landing, but it also represents the collective relief and elation of countless individuals who worked for years to make this mission a success.
A new look at the Veil Nebula uses new processing techniques to bring out fine details of the nebula’s delicate threads and filaments of ionised gas.

The Veil Nebula is supernova remnant that’s so large and bright that it can be seen from Earth in clear conditions (the best views are in the fall) with nothing more than a pair of binoculars. This new look at it from the Hubble Space Telescope uses five filters to show off the psychedelic array of ionized gases that make up its body. The nebula is about 2,100 light years away and this image is only a small piece of it. The nebula is estimated to be 130 light years wide, about 100 times wider than our own solar system.
