Science Scavenger Hunt

October 28, 2021

Astronomers may have discovered the first known exoplanet outside of the Milky Way.

According to Lisa Grossman of Science News, the planet is located in the Whirlpool galaxy which is about 28 million light-years from Earth. Astronomers say that the planet orbits both a massive star and a dead star. This discovery suggests there could be many other planets outside of our solar system to be found.

Over 4,8000 planets have been discovered orbiting other stars inside the Milky Way. Scientists know that there is no doubt that other galaxies hold planets just as our own galaxy does. However, the challenge comes during the search for the planets, considering other galaxies are lightyears away. Astrophysicist Rosanne Di Stefano explains that “they always assumed there were other planets in other galaxies, but to actually find something, is a beautiful thing. It’s a humbling experience.”

In 2018, astrophysicists began searching in archived data for objects that blocked out bright X-ray binaries. After looking through three different galaxies, only one turned up planet-like. The Saturn-sized exoplanet discovery is “quite intriguing and would be a great discovery,” says astrophysicist Ignazio Pillitteri.

Some scientists speculate how coincidental the discovery actually is to find something in such a small time frame of observation. Di Stefano counters that the observations her team has done encourages that there are many other extragalactic planets to be found.

    The throwaway lead is fine, Josie.

    Read the story aloud to see how it sounds. Time yourself. You don’t want much more than a minute, and you will be adding a comment for the broadcast.

    Now, even more exoplanets have been discovered, including those that could potentially have conditions suitable for life. There are many, many exoplanets, but it is very difficult to see them, especially in another galaxy.

    Тепер екзопланет відкрито ще більше, у тому числі ті, що потенційно можуть мати умови, придатні для існування життя. Екзопланет дуже і дуже багато, але роздивитися їх дуже складно, тим більше в іншій галактиці.
