10 feem ntau bizarre cosmic discoveries

Tib neeg tau mus txog qhov chaw tshawb kawm zoo heights. Nws yog nyob rau hauv relentless nrhiav undiscovered xav, zoo kawg wealth thiab txaus ntshai secrets lurking nyob rau hauv lub depths ntawm extraterrestrial canyons. Lub hom phiaj tseem ceeb tau raug ua tiav nyob rau hauv lub xyoo pua XX: thawj tug txiv neej ya mus rau hauv qhov chaw.

Nyob rau hauv qhov tseeb, qhov chaw muaj ntau secrets tshaj li koj muaj peev xwm xav txog tej yam. Muaj planets uas zoo yuav luag zoo li lub ntiaj teb. Tsis tas li ntawd muaj yog supermassive dub qhov, galaxies thiab nqus xov tooj cua tsis. Lawv tej zaum yuav muaj dej khov thiab av. Nws yeej tsis nkawd zaum tsis tau hais tias yeej paub nrog cog qoob loo thiab to taub qhov chaw. Tom qab tag nrho, npaum li cas tseem qhia.

Cov tsab xov xwm pib ua 11 tshiab nthuav discoveries uas ua pov thawj hais tias qhov chaw yog tseem tsis paub hais tias.

Muab ob npaug rau taws flatworms

Zaum yog ntse daws teeb meem yog tsis tshua muaj kev txhawj xeeb txog qhov teeb meem: Yog qhov chaw muaj lub neej? Yog vim li cas lawv xa muaj flatworms. Flatworms paub rau lawv regenerative powers, thiab nws yog nthuav los saib yuav ua li cas lawv yuav coj nyob rau hauv qhov chaw.

Thaum txiav mus rau hauv daim flatworms tau siab rov qab nyob rau hauv tag nrho cov kab mob no. Tab sis nyob rau hauv qhov chaw, lawv tsis yog zus: ib co ntawm lawv yog tsis revived nrog ib lub taub hau tab sis ob tug. Qhov no anomaly, uas muaj ntau yam ntawm peb twb tsis hnov txog.

Peb nyob hauv ib lub suab puam qhov chaw

Nws zoo heev coj txawv txawv tias tag nrho cov kev lom zem yog nyob deb deb ntawm peb. Lub galaxy yog heev loj heev thiab nyob deb, mus tshawb nws! Nws nkawd hais tias muaj yog vim li cas mus ntseeg tau hais tias muaj yog ib tug tsis muaj dabtsis qhov chaw, thiab peb Kab lig ntuj yog ib feem ntawm nws.

Lub ntug yog zoo li Swiss cheese. Nws muaj ib tug tuab cheeb tsam uas muaj cov galaxies, thiab qhov uas raug empty. Tsis muaj dabtsis KBC, npe hu ua tom qab nrhiav nws nyob rau hauv 2013, peb astronauts Keenan, Barger thiab Cowie, yog cov coob ntawm cov neeg uas tau puas tau cai. Nws voos kheej-kheej yog ntau tshaj 1 billion teeb xyoo.

gravitational tsis

Gravitational tsis tau muaj rau centuries, tab sis tsis muaj ib tug yuav ua pov thawj hais tias lawv tiag tiag. Thaum kawg, LIGO (Laser interferometrovaya gravitational yoj observatory) tshaj tawm nyob rau hauv Lub ob hlis ntuj hais tias lawv thaum kawg sab. Lawv pab mus rau expansion thiab contraction ntawm qhov chaw. Gravitational tsis yog ib tug tshwj xeeb cov lus qhia qhov chaw, tej khoom thiab xwm txheej uas tsim lawv. Cov ntaub ntawv no muaj peev xwm tsis tau lwm yam kev!

Xyoo no lub ob LIGO mus ntes gravitational tsis. Lawv tuaj los ntawm ob colliding dub qhov uas yuj ib ncig ntawm txhua lwm yam. Cov dab tau unseen rau ntau xyoo.

Lub ntiaj teb hli khoom siv pa

Yog, peb yeej poob tej huab cua. Nws yog tus nqi tsis ntau tshaj 90 metric tons, li ntawd, tsis muaj dab tsi txhawj txog. Nws hloov tawm hais tias ib tug me me luag hli tau txais feem ntau ntawm cov pa.

Ib txhia atoms thiab molecules rau hauv lub Upper ib feem ntawm peb cov cua thiab poob tawm mus rau hauv qhov chaw. Ib txhia ntawm lawv lub caij nplooj zeeg nyob rau hauv lunar nto, thiab thaum kawg - nyob rau hauv daim av hais tias astronauts spacecraft "Apollo" tau coj tuaj rau lub ntiaj teb. Zaum tau baffled los ntawm lub fact tias nyob rau hauv lub hli sab isotopes oxygen-18 thiab cov pa-17, uas yog nyob rau lub ntiaj teb. Tam sim no ntawm daim card yog qhia tawm!

"Ntiaj chaw ntawm lub cuaj" lurking tshaj Pluto

Soj ntsuam tiag ntseeg tias muaj yog ib tug ntiaj chaw qhov loj ntawm Neptune. Nws yeej yog heev loj thiab yog nkaum qhov chaw tshaj Pluto. Nws orbit yog tej zaum kuj distorted, vim hais tias nws yuav luag tsis yooj yim sua rau saib. Cuaj kaum, tus thiaj li hu ua "cuaj-ntiaj chaw" yuav twv yuav raug hu muaj kev cuam tshuam lub zog ntawm lwm yam lub cev nyob rau hauv lub txheej ib feem ntawm peb hnub ci system. Qhov chaw nyob rau hauv muaj lurks ib tug loj heev xilethi-aus lub cev, thiab zaum yuav sai sai no nrhiav tau nws!

Lub hnub twb poob lawm ntxaib

Tsis ntev los no kev tshawb fawb qhia tias feem coob ntawm cov hnub qub yog yug los muaj tsawg kawg yog ib tug luag. Cov nyob ze cov neeg nyob ze yog lub hnub, Alpha Centauri yog fraught nrog tsis ib tiam sis peb cov hnub qub! Tam sim no zaum no ntau dua puas tau ntseeg hais tias peb tus kheej hnub ib zaug muaj ib tug ntxaib. Conventionally, nws yog hu ua Nemesis.

Feem ntau cov yuav, nws tsis yog ib tug loj loj ntxaib, nws cia li ploj ntais mus rau hauv lub kab lig ntuj txoj kev, tsis tawm hauv tej qhov cim tseg. Zaum ntseeg tau hais tias qhov no yog txoj hmoo ntawm feem ntau ntawm cov binary hnub qub uas yog cia li nyob rau hauv ntau txoj kev.

Jupiter zoo nkauj

NASA spacecraft "Juno" twb nyuam qhuav mus txog Jupiter. Qhov no davhlau muab tib neeg ib co ntawm cov feem ntau surreal thiab exciting dluab ntawm giant ntiaj chaw tsim. Txawm tias tseem tsis tau ua tej yam loj scientific discoveries, cov duab noj junocam, cam hais tias cov neeg yuav tsum tsis txhob ya deb heev yuav txaus siab rau txoj kev zoo nkauj ntawm lub ntug. Txhaj tshuaj noj nrog lub "Juno" tsuas txaus!

Cov loj loj dej khov ntawv rau ntawm Mars

Mars hides ib tug ntawm cov loj tshaj plaws dej khov tso, paub rau noob neej. Nws yog roughly qhov luaj li cas ntawm New Mexico, thiab muaj txog li 85% dej thiab tus so ntawm tus txheem - mas av nkos. Lub volume ntawm cov dej khov yog tiag tiag amazing - nws surpasses Lake Superior, uas muaj ntau tshaj li 12,000 nyhav kilometers ntawm cov dej.

Tsev blocks ntawm lub neej

Cov molecules ntawm methyl isocyanate tau kuaj nyob rau hauv cov hmoov av thiab cov pa uas puag ncig lub protostar. Lawv yog cov zoo heev rau peb hnub nyob rau hauv thaum pib ntawm nws lub neej. Nws yog ntseeg hais tias lub ntiaj teb thiab lwm lub planets raug tsim los ntawm cov khoom sab laug tom qab tsim ntawm peb hnub. Yog li, los ntawm kev kawm hluas cov hnub qub, zaum ze zog mus rau to taub yuav ua li cas lub neej pib nyob rau hauv lub ntiaj teb! Tsis rau thawj lub sij hawm lub zej lub zos ntawm Amas (Atacama Loj millimeter / sub-millimeter Array) pom ib yam dab tsi interesting. Tsis ntev dhau los, ib pab neeg ntawm astronomers ua ib qho kev nthuav foundations nyob rau hauv cov roj nyob ib ncig ib tug hluas hnub qub, muaj tiag tiag qab zib molecules.

Proxima b - Tshiab ntiaj teb

Proxima Centauri - yog ib lub hnub qub, uas yog tsuas ib tug ob peb kauj ruam ntawm lub tshav ntuj daim av ntawm lub teeb. Mus cuag nws, nws yuav tsum 4.2 teeb xyoo. Zaum muaj sab lub ntiaj chaw nyob rau hauv lub thiaj li hu ua habitable tsam. Nyob rau Proxima Centauri kua dej yuav nyob ua ib ke, uas yog tsub kom tau txoj kev rau txoj kev loj hlob ntawm lub neej nyob rau nws.

Dubbed Proxima b - qhov no tshiab khiv pom ntiaj chaw. Nws muaj ib tug loj zoo ib yam li lub ntiaj teb txoj kev loj. Foundation board neeg npe hu Txhob Foundation Mark Zuckerberg, Stiven Hoking, thiab Yuri Milner tshaj tawm hais tias lawv yuav tsim ib tug spaceship qhov luaj li cas ntawm ib tug microchip mus tshawb inhabited worlds. Peb tes num lub npe hu ua txhob Starshot.

Nrog rau cov discovery ntawm Proxima b nws yog yuav hais tias lub ntiaj chaw yuav ua ib lub hom phiaj rau tus qauv tshiab ntawm lub spacecraft.
