Citizen Scientists Find a Star Escaping the Milky Way

This artist's concept shows a hypothetical white dwarf, left, that has exploded as a supernova. The object at right is CWISE J1249, a star or brown dwarf ejected from this system as a result of the explosion. This scenario is one explanation for where CWISE J1249 came from. W.M.

Citizen science is such a great concept. Using the combined computing power of a gazillion (exaggeration) desktop and laptops to churn through data is an excellent and efficient way of analysing volumes of data. This has been shown yet again as a star has been identified to be hurtling out to intergalactic space! Most stars in the Milky Way are not travelling fast enough to be able to escape its immense gravity but the suspected brown dwarf is travelling at 1.5 million km/h, fast enough to escape.

Even Citizen Scientists are Getting Time on JWST

This artist’s illustration shows a dim, cold brown dwarf in space. Brown dwarfs form like stars, but do not have enough mass to ignite nuclear fusion in their cores – the process that causes stars to burn. As a result they share some physical characteristics with massive planets, like Jupiter. Credits: IPAC/Caltech

Over the years, members of the public have regularly made exciting discoveries and meaningful contributions to the scientific process through citizen science projects. These citizen scientists sometimes mine large datasets for cosmic treasures, uncovering unknown objects such as Hanny’s Voorwerp, or other times bring an unusual phenomenon to scientists’ attention, such as the discovery of the new aurora-like spectacle called STEVE.  Whatever the project, the advent of citizen science projects has changed the nature of scientific engagement between the public and the scientific community.  

Now, unusual brown dwarf stars discovered by citizen scientists will be observed by the James Webb Space Telescope, with the hopes of learning more about these rare objects. Excitingly, one of the citizen scientists has been named as a co-investigator on a winning Webb proposal.
