mkuu kumbuka kuwa galaxy ni mkusanyiko wa nyota milioni kadhaa na sayari za kila nyota, gases and other objects. Jua letu ni nyota. Na kutoka nyota hadi nyota nyingine kipimo chake ni spidi ya mwanga. sisi hapa tulipo tupo kwenye galaxy inaitwa milky way, kwahiyo unapoongelea joto nadhani katika galaxy ni kila nyota ina joto lake lakini nyota kama jua letu ni nyuzi 5500, na kila sayari joto lake linategemea umbali wake kutoka kwenye jua lake, zingine ni barafu tu kama pluto, majua mengine i hope ni zaidi ya au kidogo.
Ila jua letu linazeeka na kufa kwake ni kubasti. Mwisho wa maisha maana uhai wa viumbe hai na sola system yetu unategemea jua na activity zake.

Kufika kwenye galaxy nyingine nadhani bado sana, nadhani wanasayansi wamefaniki wa kupeleka chombo hadi sayari ya mwisho kwa jua letu, bado hata hatujafikisha chombo chetu kwenye sayari za jua lingine jirani. Ila camera ziko poweful kuona yote hayo yanayosemwa na wanasayansi, kilasiku kuna uvumbuzi wa mambo mapya.

Mwanga kutoka juani kutufikia hapa duniani inachukua dakika nane mfano jua lingezima gafla ingekuchua dakika nane kujua hakuna mwanga na kuanza kusikia baridi.
Pia ukumbuke kuwa mwaga unasafiri kwa spidi ya kilomita laki 3 kwa sekunde.

Kutoka jua letu mpaka jua lingine kwenye galaxy yetu, umbali wake unapimwa kwa spidi ya mwanga. kama ulivyoona mwanga unatufikia baada ya dakika 8 kutoaka jua letu, ila kwa jua lingine lilio karibu ya sola sysytem yetu mwanga wake unatufikia baada ya miaka 4!

Kuna nyota tunaziona angani usiku zingine zimesha kufa ila mwanga wake ulikua haujafika maana zingine mwanga wake unachukua miaka milioni kadhaa kutufikia...haya wakuu.

nyota zinakufaje mkuu

nyota zinakufaje mkuu

Mkuu, jua ni kama nyota zingine uzionazo angani. Kama unavyowasha jiko waweza kutumia mafuta ya taa, mkaa n.k. Jua linatumia hydrogen gas, kwa process inaitwa nuclear fusion nakuweza kuwaka na kutupa mwanga, joto n.k. ili nyota iitwe nyota ni lazima iwe na mfumo huo wa kujitengenezea energy kutoa mwanga, ku-survive....na hii gesi huisha na ndio mwisho wa maisha ya nyota...
Ndio hapo wataalamu wanasema nyota imekufa.
Nadhani zipo njia nyingine nyota yaweza kuzaliwa au kufa...kwa kuungana na nyota nyingine....matokeo ya galaxies mbili kuungana....etc..
Kwa ujazo uliopo wa hydrogen kwenye jua letu, linakadiriwa litakaa zaidi ya miaka bilioni 5 na kuanza kufifia mwishowe kufa. Pia inasemekana limezaliwa miaka bilioni 4.5

Duh, hiyo miaka billion 5 siwezi fika huko, labda kizazi change cha million 100 au zaidi ya hapo.

One Star Over, a Planet That Might Be Another Earth
204

Another Earth could be circling the star right next door to us.

Astronomers announced on Wednesday that they had detected a planet orbiting Proxima Centauri, the closest neighbor to our solar system. Intriguingly, the planet is in the star’s “Goldilocks zone,” where it may be neither too hot nor too cold. That means liquid water could exist at the surface, raising the possibility for life.

Although observations in recent years, particularly by NASA’s Kepler planet-finding mission, have uncovered a bounty of Earth-size worlds throughout the galaxy, this one holds particular promise because it might someday, decades from now, be possible to reach. It’s 4.2 light-years, or 25 trillion miles, away from Earth, which is extremely close in cosmic terms.

One astronomer likened it to a flashing neon sign. “I’m the nearest star, and I have a potentially habitable planet!” said R. Paul Butler, an astronomer at the Carnegie Institution for Science and a member of the team that made the discovery.

Guillem Anglada-Escudé, an astronomer at Queen Mary University of London and the leader of the team that made the discovery reported in the journal Nature, said, “We know there are terrestrial planets around many stars, and we kind of expected the nearby stars would contain terrestrial planets. This is not exciting because of this. The excitement is because it is the nearest one.”

Beyond the planet’s size and distance from its parent star, much about it is still mysterious. Scientists are working off computer models that offer mere hints of what’s possible: Conditions could be Earthlike, but they could also be hellish like Venus, or cold and dry like Mars.

There is no picture of the planet, which has been designated Proxima b. Instead, Dr. Anglada-Escudé and his colleagues detected it indirectly, studying via telescope the light of the parent star. They zeroed in on clocklike wobbles in the starlight, as the colors shifted slightly to the reddish end of the spectrum, then slightly bluish. The oscillations, caused by the bobbing back-and-forth motion of the star as it is pulled around by the gravity of the planet, are similar to how the pitch of a police siren rises or falls depending on whether the patrol car is traveling toward or away from the listener.


From the size of the wobbles, the astronomers determined that Proxima b is at least 1.3 times the mass of Earth, although it could be several times larger. A year on Proxima b — the time to complete one orbit around the star — lasts just 11.2 days.

Although the planet, lost in the glare of the star, cannot be viewed by current telescopes, astronomers hope to see it when the next generation is built a decade from now.

And the planet’s proximity to Earth gives hope that robotic probes could someday be zooming past the planet for a close-up look. A privately funded team of scientists and technology titans, led by the Russian entrepreneur Yuri Milner and the theoretical physicist Stephen Hawking, have announced Breakthrough Starshot Initiative, a project to develop and launch a fleet of iPhone-size spacecraft within two to three decades. Their proposed destination is the Alpha Centauri star system, which includes two larger, sunlike stars in addition to Proxima Centauri.

“We will definitely aim at Proxima,” said Avi Loeb, a Harvard astronomer who is the chairman of an advisory committee for Breakthrough Starshot. “This is like finding prime real estate in our neighborhood.”

This newly discovered planet is much closer to its parent star, about five million miles apart, than Earth is to the sun, 93 million miles. Even Mercury, the innermost planet of our solar system, is 36 million miles from the sun.

While Proxima b might be similar to Earth, its parent star, Proxima Centauri, is very different from the sun. It is tiny, belonging to a class of stars known as red dwarfs, with only about 12 percent of the mass of the sun and about 1/600th the luminosity — so dim that it cannot be seen from Earth with the naked eye.

Thus Proxima b, despite its closeness to the star, receives less warmth than Earth, but enough that water could flow on the surface. Whether the planet has liquid water or an atmosphere is “pure speculation at this point,” Dr. Anglada-Escudé said in a news conference.

If the planet formed close to the star, it could be dry and airless, but it might also have formed farther out and migrated inward to its current orbit. It is also possible that the planet formed dry and was later bombarded by comets or ice-rich asteroids.

“There are viable models and stories that lead to a viable Earthlike planet today,” Dr. Anglada-Escudé said.

Even if it is habitable, scientists studying the possibility of life elsewhere in the universe spiritedly debate whether planets around these red dwarfs are a promising place to look.

Small stars are more erratic, especially during their youth, and eruptions off the star’s surface could strip away the atmosphere from such planets. Levels of X-rays and other high-energy radiation bombarding the planet would be 100 times that on Earth, the scientists said.

Jua ni matokeo ya kitendo kiitwacho fusion ya element iitwayo hydrogen I hivyo jua ni kama gesi fulani yenye umbo la mviringo nayo inatoa joto Kali sana 5500°c

Juu ni mujibu wa watafiti wanavyosema

Moto ili uweze kusurvive kunakuwa na oxygen je na kwenye jua kuna oxygen..? ama lenyewe ni muundo tofauti na ninavyodhani..?

Hakuna moto hapo Bali kuna nishati inayotolewa kutokana na hiyo fusion process nishati yenyewe ndo joto

UNDER THE RIGHT CONDITIONS OUR SUN COULD PRODUCE AN ENORMOUS SUPERFLARE


IT'S THE END OF THE WORLD AS WE KNOW IT

Superflare

An artist's impression of what a superflare might look like on our own sun

Solar flares are gorgeous, but the delicate fiery loops that we've observed during humanity's brief study of the sun are nothing compared to what other, similar stars are up to.

In arecent paper, researchers detail their observations of 'superflares' on a binary star in our galaxy named KIC 9655129. These superflares are huge solar flares that are much larger than any that we've observed coming off our own sun.

But even though they differ in terms of magnitude, (a superflare might give off the energy of a billion-megaton bomb while our sun's solar flares reach a piddling 100 million megaton-bomb) researchers discovered that the underlying processes that drive the superflares on other stars is the same basic engine that drives solar flares on our own stars--periodic oscillations of magnetically charged plasma within the interior of the sun. So, could it happen here? Maybe. But if it did, the results would be very bad.

“If the Sun were to produce a superflare it would be disastrous for life on Earth; our GPS and radio communication systems could be severely disrupted and there could be large scale power blackouts as a result of strong electrical currents being induced in power grids," lead author of the paper, Chloë Pugh, said in astatement.

But stop your panicked screenplay writing. According to Pugh, “[T]he conditions needed for a superflare are extremely unlikely to occur on the Sun, based on previous observations of solar activity.”

And if the sun did ever produce a superflare, or just a really large regular flare, we'd at least have a little bit of warning that it's headed our way. Newforecasting techniquesfor solar weather combined withbetter observational equipment like the DSCOVR satellitemeans that even if the worst is on its way, we can still try to get ready for it.

Mkuu hivi kwanini kutoka duniani Venus ni mbali zaidi kuliko kwenda kwenye jua ili hali tunaelezwa Venus ni sayari ambayo ipo na jua?

Mkuu hivi kwanini kutoka duniani Venus ni mbali zaidi kuliko kwenda kwenye jua ili hali tunaelezwa Venus ni sayari ambayo ipo na jua?

Mkuu Venus ipo umbali wa kilomita 107.4 millions kutoka juani wakati mwingine 108.9 millions. Orbit haipo duara kamili, ipo kama yai (elliptical).

Dunia ipo mbali zaidi kuliko venus,
