For astronomers like me, this query has proved difficult — so difficult that we have been very almost fooled when the primary recorded interstellar object, named ‘Oumuamua, was noticed passing by way of the internal photo voltaic system in 2017.

Astronomers as soon as thought that any object transferring beneath its personal pace, with no seen technique of propulsion, must be synthetic know-how. We knew how ‘Oumuamua ought to behave if it have been an interstellar house rock, or so we thought, however in each manner it acted the precise reverse.

As ‘Oumuamua sped by way of the photo voltaic system, we solely had a number of weeks throughout which we have been in a position to monitor it with our telescopes the world over. These observations confirmed that the thing got here from outdoors the photo voltaic system, and was extraordinarily elongated and tumbling. ‘Oumuamua displayed no comet-like tail however nonetheless moved beneath its personal propulsion. 

Comets additionally transfer beneath their very own propulsion, however they show lovely tails attributable to mud and ice blown off their surfaces, which additionally causes a rocket-like recoil. ‘Oumuamua was completely different. Its mysterious flight by way of our photo voltaic system sparked whispers of a man-made provenance. Some astronomers even called it Rama.  

The true clarification, which we decided from its movement and the quantity of vitality it obtained from the solar, is simply as unusual: a wholly new type of object. We name them “darkish comets.” Since we noticed ‘Oumuamua, we have now discovered a inhabitants of seven darkish comets hiding amongst our photo voltaic system’s asteroids. They get their identify as a result of they transfer like a comet, however show no mud tail.  

Guests from past the photo voltaic system — interstellar vacationers — have lengthy been predicted by science fiction writers like Arthur C. Clarke, however in actuality, it is not really easy to determine what we’re seeing — or simply what number of interstellar house rocks, or spaceships, are in Earth’s neighborhood at a given time. This problem got here to a head as we rushed to make sense of ‘Oumuamua, however with new telescopes just like the James Webb Area Telescope (JWST) and the forthcoming Rubin Observatory Legacy Survey of Area and Time (LSST) within the Atacama Desert in Chile, we’ll have the instruments we have to make sense of future interstellar vacationers — and increase our understanding of the cosmos.  

If solely we would had the JWST when ‘Oumuamua was found, we might have been in a position to take extra detailed photographs of the thing and get details about the way it seemed in numerous wavelengths of sunshine. By doing this, we might have higher understood what was propelling it by way of house. We might have seen molecules like water or carbon dioxide that solely present up at sure wavelengths and do not mirror daylight. We routinely see regular photo voltaic system comets being propelled as their surfaces warmth up and water and carbon dioxide ice remodel into fuel. We might have recognized it instantly as a darkish comet-like object. The excellent news is, if we spot one other ‘Oumuamua, we have already got an authorized JWST program to observe it.  

Associated: James Webb Area Telescope (JWST) — An entire information

Sooner or later, the JWST will not be the one highly effective software in our toolkit. The LSST, set to come back on-line within the subsequent 12 months or so, ought to detect many extra interstellar objects and be capable of determine darkish comets in our personal photo voltaic system. Positioned within the Atacama Desert, a main spot for viewing the heavens, the LSST will begin scanning your entire Southern Hemisphere sky virtually each night time. The LSST will be capable of spot a lot fainter objects than any of our surveys that at the moment monitor your entire sky for quickly transferring objects. It is going to be in a position to detect mysterious objects like ‘Oumuamua which are dimmer, both as a result of they’re smaller or farther away from the Earth. The LSST will even be capable of discover many extra smaller asteroids, and can be capable of spot if they’re darkish comets and transferring beneath their very own propulsion. 

It is potential that when the LSST makes first gentle, we are going to begin detecting interstellar objects on a month-to-month — and even weekly — foundation. A few of these could also be darkish like ‘Oumuamua, and a few could also be brighter with lovely tails, just like the second interstellar comet, 2I/Borisov.   

It could prove that the sky near the Earth is teeming with interstellar objects even smaller than ‘Oumuamua, all of which have been invisible up till now. These small interstellar guests might fairly plausibly be constantly whizzing by way of the Earth’s neighborhood inside the photo voltaic system. If that finally ends up taking place, then the LSST would possibly spot an interstellar goal shut sufficient for a devoted house mission.  

Shut encounters with an interstellar customer will now not be a subject reserved for science fiction writers. 

With the LSST and JWST, we have now the instruments to inform the distinction between an clever customer and an interstellar darkish comet. Let’s not get fooled.
