And the Webb telescope is going much further out into space than Hubble, meaning there will be no chance for humans to visit it for repairs should anything go wrong. That won't happen until at least 2018, however, and it's a mission that - like many - has already suffered delays and gone way over budget. The Webb telescope will peer even deeper into the night sky, bringing us closer to seeing the very first stars ever formed. It has a mirror that is six times larger than Hubble's and will be at least 100 times as powerful. One thing we do know is that the Hubble's successor, the James Webb Space Telescope, is going to be even better. If Hubble can avoid another one of those, it's likely the telescope will continue to operate well into the 2020s. And the Kepler Space Telescope has been helping us find other planets in our own galaxy since 2009, even after a massive mechanical failure. After all, the Opportunity rover, which landed on Mars in 2005, is still roaming the surface and gathering data - even though it was only supposed to last around 90 days. Hubble's days are numbered, but it's not totally clear when it will close its eye for the final time one thing NASA is excellent at is getting extra value out of its missions. Lee Billings took some time at Scientific American to laud Hubble's unsung images, the ones that won't necessarily wow you but mean a great deal to the project and to our understanding of the universe.Įlsewhere, Vox has a great breakdown of one of Hubble's most famous images, Discover assembled a detailed timeline, and National Geographic tells you why Hubble images appear in color (they're really photographed in black and white) and includes a must-see interactive feature that breaks down how the telescope works, piece by piece. The New York Times put together a good explainer video of how the Hubble works and spoke to some astronomers about their favorite images they took with the space telescope. Phil Plait, who runs Slate's "Bad Astronomer" blog and worked on Hubble for a number of years, wrote some great explanations of some of the most famous images to come from the project. Nature spoke to more than a dozen scientists and Hubble team members to compile a wonderful oral history of the telescope. Being the 25th anniversary, the amount of tributes on the internet to Hubble is vast.
