Wɔhwɛ kwan sɛ Neil Gehrels Swift Observatory bɛsan aba Asase ewim mu Wukuda, na ɛbɛhyew wɔ saa adeyɛ no mu
Nasa n’ Neil Gehrels Swift Observatory, a adi mfe aduonu rehwehwɛ nkabom a ano yɛ den sen biara wɔ wim no mu no, wɔhwɛ kwan sɛ ɛbɛsan aba Asase wim mframa no mu Wukuda, na ɛbɛhyew wɔ saa adeyɛ no mu.

“Mmeae a afaafa biara a aka betumi asan aba no betumi asesa fi hemisphere baako so akɔ foforo so na egyina bere a ɛsan ba no so,” agyesidua no kae wɔ blogpost mu, na ɔde kaa ho sɛ mmeae a aka no yɛ nea ɛda ntam wɔ anaafo latitude 20.6 ne atifi latitude 20.6 ntam.
Ɛkwan no de kaa ho sɛ: “Asiane a ɛbɛto obiara a ɔwɔ asase so no yɛ nea ɛnsɛ sɛ ɛba – bɛyɛ 1 wɔ 2,100 mu. NASA ne Space Force bɛkɔ so ahwɛ sɛnea ɛresan aba mu no na wɔayɛ nkɔmhyɛ no foforo.”
Wɔde ɔsorohwɛbea no baa adwuma mu wɔ afe 2004 mu sɛ ɛbɛhwehwɛ amansan mu nneɛma a emu yɛ den a ɛpae, a wɔfrɛ no cosmic gamma-ray bursts, na ntɛm ara akyɛde ne nhwehwɛmu a ɛfa baabi a ɛwɔ ne tumi a ɛwɔ no asan aba Asase so.

Wɔde Swift bae sɛ Nasa n'ano a wɔde ɛyɛ, anaa Midex, nhyehyɛeɛ no fa bi. Wɔ July mu no, ɛhunuu mega black hole kɛse bi a ɛnante baabiara a ɛtetee nsoromma mu, a ɛba bere a nsoromma bi twamu bɛn supermassive black hole bi kɔsi baabi a ɛde owuo ba.
“Nsoroma a ɛrebubu no mu nkakrankakra no yɛ hyew bere a ɛrekyinkyin wɔ black hole no ho no, na ɛbɔ hann a nsoromatorfo tumi hu fi akyirikyiri wɔ amansan no mu, na black hole no tow relativistic jet kɔ wim,” sɛnea agency no kae no.
Blak hole no, a wɔaka ho asɛm sɛ ɛyɛ “egyaa” no, hyerɛnee bere a na ɛrewe nsoromma no wɔ galaxy bi ano, nea nyansapɛfo frɛ no “tidal disruption event”. Ɛkame ayɛ sɛ galaxy biara wɔ supermassive blak hole kɛse wɔ ne mfinimfini, na tidal disruption ba bɛyɛ pɛnkoro wɔ mfe 100,000 biara mu.

“Yɛrehwehwɛ saa nsoromma a ɛtetew mu yi sɛ ɔkwan a yɛbɛfa so ahu black hole akɛseɛ a wɔnhu wɔn a wɔretu afri galaxy no mfimfini a wɔtaa tena hɔ,” saa na Robert Stein, obi a ɔyɛ nhwehwɛmu fellow wɔ University of Maryland, College Park, ne Nasa Goddard Space Flight Center a ɛwɔ Greenbelt, Maryland, kaa saa saa bere no.

Deɛ wɔnnim ara ne sɛdeɛ saa black hole no bɛhyɛɛ aseɛ nantee akɔ akyirikyiri saa. Stein kaa sɛ ebia ɛhyɛɛ aseɛ wɔ galaxy ketewa bi mu a ɛne kɛseɛ no bɔɔ mu, nanso asɛm titiriw a ɛwɔ mu ne sɛ black hole a ɛkyinkyini no abu so sɛn.
