Ibuti la Jauza imeshaendelea kufikia ngazi za mwisho |
Ibuti la Jauza imeshaendelea kufikia ngazi za mwisho za [[mageuzi ya nyota]] (''[[:en:stellar evolution|stellar evolution]]''). Katika kipindi cha miaka milioni 1 ijayo inakadiriwa kutimiza mageuzi yake hadi kulipuka kama [[nyota ya nova]]. <ref>{{cite web|url=http://www.esa.int/Our_Activities/Space_Science/Betelgeuse_braces_for_a_collision |title=Betelgeuse braces for a collision |publisher=ESA |date=2013-01-22 |accessdate=2013-01-23 }}</ref> |

Ibuti la Jauza (jina la kisayansi Alpha Orionis, ing. Betelgeuse) ni nyota ya aina jitu nyekundu inayoonekana katika kundinyota Sayadi (Orion). Ni nyota ang'avu ya tisa kati ya nyota zote zinazoonekana angani na nyota ang'avu ya pili kwenye Sayadi (Orion). Ung'avu wake unachezacheza kati ya vipimo vya 0.2 na 1.2.[1]
Umbali wake na dunia ulikadiriwa mnamo mwaka 2008 kuwa miaka ya nuru 640[2]
Umri wa Ibuti la Jauza hautimizi miaka milioni 10 lakini umeendelea haraka kutokana na masi yake kubwa. [3]
Ibuti la Jauza imeshaendelea kufikia ngazi za mwisho za mageuzi ya nyota (stellar evolution). Katika kipindi cha miaka milioni 1 ijayo inakadiriwa kutimiza mageuzi yake hadi kulipuka kama nyota ya nova. [4]
