Could an invisible major planet lurk at the border of oursolar system of rules ? Can black hole reverberate through outer space like intergalactic billiard ballock ? Did our own galaxy ’s black trap " wake up " with a bang millions of years ago — and could it do so again ?
These may not be the questions that first drove humans to study the stars one thousand of geezerhood ago . But , as astronomers see ever deeply into the moth-eaten corners of the cosmos , peculiar discoveries have ram them to grapple with ever - stranger interrogative about the nature of our universe and the limits of what could be lallygag out there .

From our own cosmic backyard to the distant deepness of the other population , here are five of the most cryptic objects that scientists have discover in space — and the good explanation for what they are .

— 8 strange objects that could be hide out in the out solar system
Far beyond the orbit of Neptune , a mysterious , massive entity may be moving through the ring of frigid objects that surrounds oursolar system . scientist studying this region have found that the sphere of more than a dozen rocky objective are being subtly alter , as if being tug on by the gravity of an enormous , unobserved satellite — a theoretic object known as Planet Nine .
This secret Earth is estimated to be anywhere from five to 10 time as monolithic as Earth and to take up to 10,000 year to complete a single field of the sun . But besides the strange " kink " in the orbits of nearby objects , there is still no concrete grounds of Planet Nine ’s being . If it ’s out there , lento orbiting more than 500 times farther from the sun than Earth does , the inscrutable Earth is far too dim to detect with current telescopes .
However , the forthcomingVera C. Rubin Observatory , which is currently under building in Chile and will eventually put down a 10 - year meter - reverting video of the night sky , should be able to spot more evidence of the elusive world — potentially confirming or denying its existence once and for all .
The “runaway black hole”
In April 2023 , astronomers reported the catching of something never seen before : a " runaway " opprobrious trap , untethered from any galax and blazing through blank at 4,500 times the upper of speech sound with an tremendous trail of star topology streaking behind it .
The black hole is approximate to be 20 million time the peck of Earth ’s sun , while its bright tail could measure more than 200,000 light - years long ( about twice the diam of theMilky Way ) . observation from the Keck telescope in Hawaii find that one conclusion of this star trail looks like linked to a distant nanus galaxy , from which the freewheeling pitch-black hole may have been astronomically yeeted .
smutty holesform the affection of large galaxies like ourMilky Way , drop anchor the wall gas , dust and lead organization in place . So how can one of these cosmic monster simply vamoose ? harmonize to the study source , it ’s potential that the black fix once orbited a second pitch-black hollow in a rarified binary arrangement — then , when a third black hole was introduced to the organisation during a galaxy merger , the chaotic gravitational interactions sent one black jam flying into the wild black yonder . Ifconfirmed by follow - up studies , this will be the first grounds that black holes can head for the hills their extragalactic nebula .

James Webb telescope’s JUMBOs
Black holes are not the only cosmic blowout ; planets have also been spot on the lam , and in far capital number . In 2023 , theJames Webb Space Telescope(JWST ) detectedmore than 500 free - float " rogue " planetscareening through the Orion Nebula . rough 80 of these were discern orbiting each other in binary pairs — a phenomenon with no clear account . Because these rogue worlds are roughly as large as Jupiter , scientists make them Jupiter - mass binary objects — or JUMBOs .
NASAestimates that there may betrillions of rogue planetswandering our galaxy , many of which were shunted out of domain during the chaotic early daylight of star system organisation . However , current models bomb to explain the existence of JUMBOs . One possibility suggests that these eccentric objects imprint directly from break down clouds of gas and debris in interstellar distance , in a scaled - down version of how star form . Another possibility says a passing star could have pushed the objects out of orbit , but models have shown thatthis explanation is highly unlikely . For now , JUMBOs posture a jumbo - size mystifier for astronomers .
The Fermi bubbles
The black jam at the center of our coltsfoot is ( hopefully ) not go anywhere anytime soon , but it has acted up in unexpected ways in the not - too - upstage past . Astronomers can see the grounds of massive , energetic eruptions from our dark hole in the form of two sets of gargantuan bubble — known as theFermi bubblesandeROSITA bubbles — that tower over our galaxy . These overlapping lobes of energy span the center of the Milky path like an tremendous hourglass , stretching roughly 25,000 light - year above and below our central black mess . valuate together , the bubbles span about half the width of the galax itself .
Despite their extraordinary sizing , you ca n’t see them in the sky ; the Fermi bubble , filled with tight - moving corpuscle called cosmic ray , can be blemish only by scope that find gamma - rays , while the eROSITA bubble — fill with extremely hot gas — are seeable only as cristal - ray .
Astronomers do n’t know exactly how the bubble spring , but a 2022 bailiwick suggested that they are the result of a gargantuanblack hole explosion that lasted more than 100,000 yr , beginning close to 2.6 million years ago , when vast quantity of matter swarm into our smutty golf hole ’s maw . If confirm , this conjecture would intimate that our black hole was alive much more recently than once thought .

The big question
While study a curious spot of starlight known as Herbig - Haro 46/47 , JWST blot something even more mysterious in the remote background of its image — a deep - blank swoop of hot gasshaped absolutely like a question mark .
It ’s unclear exactly what the aim is or how far aside it is , but its reddish colour in JWST images evoke that the object is exceptionally ancient , with its light stretching into ever - redder wavelengths as it crosses vast cosmic distance to reach us . It may be a galaxy , or perhaps several galaxies in the midst of ripping each other aside during a chaotic amalgamation , research worker told Live Science ’s sister siteSpace.comin 2023 .
Whatever it may be , the cosmic enquiry mark is just one of many puzzle introduce by JWST ’s innovational observation . uncover its identity operator may have to take a back seat to more urgent question — like , are wecompletely awry about our understanding of the universe of discourse ?
The gargantuan Fermi Bubbles are only visible in gamma-ray light.
