Hubble Celebrates 35th Year In Orbit

To celebrate the Hubble Space Telescope's 35th anniversary in orbit, NASA and ESA released a series of new, out-out-of-this-world images spanning planets, nebulae, and galaxies. From a press release: Hubble today is at the peak of its scientific return thanks to the dedication, perseverance and skills of engineers, scientists and mission operators. Astronaut shuttle crews gallantly chased and rendezvoused with Hubble on five servicing missions from 1993 to 2009. The astronauts, including ESA astronauts on two of the servicing missions, upgraded Hubble's cameras, computers and other support systems. By extending Hubble's operational life the telescope has made nearly 1.7 million observations, looking at approximately 55,000 astronomical targets. Hubble discoveries have resulted in over 22,000 papers and over 1.3 million citations as of February 2025. All the data collected by Hubble is archived and currently adds up to over 400 terabytes. The demand for observing time remains very high with 6:1 oversubscriptions, making it one of the most in-demand observatories today. Hubble's long operational life has allowed astronomers to see astronomical changes spanning over three decades: seasonal variability on the planets in our solar system, black hole jets traveling at nearly the speed of light, stellar convulsions, asteroid collisions, expanding supernova bubbles, and much more.
