If sound could travel through space, the sound of the sun would be too much for human eardrums and they would rupture...

Not to mention all the impacts that occur in the asteroid belt.

Geyser Season on Mars

This Oct. 29, 2018, image from the HiRISE camera on NASA’s Mars Reconnaissance Orbiter captures geysers of gas and dust that occur in springtime in the South Polar region of Mars. As the Sun rises higher in the sky, the thick coating of carbon dioxide ice that accumulated over the winter begins to warm and then turn to vapor. Sunlight penetrates through the transparent ice and is absorbed at the base of the ice layer. The gas that forms because of the warming escapes through weaknesses in the ice and erupts in the form of geysers.

HiRISE, or the High Resolution Imaging Science Experiment, is a powerful camera that takes pictures covering vast areas of Martian terrain while being able to see features as small as a kitchen table.

A Stellar Bouquet

This image, released on Feb. 12, 2025, is the deepest X-ray image ever made of the spectacular star forming region called 30 Doradus. By combining X-ray data from NASA’s Chandra X-ray Observatory (blue and green) with optical data from NASA’s Hubble Space Telescope (yellow) and radio data from the Atacama Large Millimeter/submillimeter Array (orange), this stellar arrangement comes alive.

Otherwise known as the Tarantula Nebula, 30 Dor is located about 160,000 light-years away in a small neighboring galaxy to the Milky Way known as the Large Magellanic Cloud. Because it one of the brightest and populated star-forming regions to Earth, 30 Dor is a frequent target for scientists trying to learn more about how stars are born.

Learn more about this new image and what it reveals.
