00:00When I began with the Sungrazer project, we had less than a thousand comets, that was over 20 years ago.
00:06So the fact that we've finally reached this milestone, 5,000 comets, is just unbelievable to me.
00:13Sungrazer project is a project that allows anyone, anywhere in the world, to sit down with a laptop and discover comets.
00:22The clue to what a sun grazing comet is kind of in the name there, it's literally a comet that grazes by the sun.
00:28The Sungrazer project relies exclusively on images of the sun from spacecraft,
00:35and the images that we discover nearly all of our comets in, come from the Solar and Heliospheric Observatory, or SOHO.
00:44That is a satellite that was launched in 1995, so it's been operating for a long time now.
00:513, 2, 1, ignition, and liftoff of SOHO and the Atlas vehicle on an international mission of solar physics.
01:01Our participants go to the SOHO website, where we have all of our latest images from the spacecraft,
01:08and they download those images, and it's really as simple as looking through them, flicking through the image,
01:14looking for something tiny and faint, and moving in a different direction to the stars.
01:21Discovering a comet is a very unique feeling.
01:25You have this realization that suddenly you've found a piece of the solar system, a piece of the universe, that no one has ever seen before.
01:33Prior to the launch of the SOHO mission and the Sungrazer project, there were only a couple of dozen sun grazing comets on record.
01:43That's all we knew existed.
01:45The 5,000 comet milestone is a huge achievement. It's one that none of us dreamed we would even get to.
01:52So simply the statistics of 5,000 comets and looking at their orbits and trajectories through space is a super unique data set.
02:03It's a really valuable science.
02:05And it is just a testament to the countless hours the project participants have put into this.
02:13We absolutely would not, under any circumstance, be here if it wasn't for what our project volunteers have done.
02:20That's really what 5,000 comets represents.
02:23It's 20 or more years of invaluable discoveries from the project volunteers.
