Mbiri ya mapulaneti kudzera pakupezeka kwa Exoplanet wachichepere.

Akatswiri a zakuthambo ochokera ku United States apeza exoplanet, imazungulira imodzi mwa nyenyezi zowala kwambiri; kuyambitsa lingaliro lamomwe matupi am'mapulaneti angapangidwire. Zimanenedwa kuti exoplanet ndi pulaneti yomwe ikuzungulira nyenyezi yosiyana ndi yathu, osati ya dzuwa lathu.

Kafukufukuyu adachitidwa ndi The Astrophysical Journal Letters, yemwe adatcha pulaneti DS Tuc Ab, pomwe nyenyezi imanenedwa kuti ndiyomwe amakhala; Dziko lino lili zaka pafupifupi 45 miliyoni, ndiye kuti, nthawi ya mapulaneti imadziwika kuti ndiyotsogola.

Malinga ndi ofufuza a Dartmouth College: Exoplanet sikukula. Komabe, akadali achichepere zimasinthabe monga kuwonongeka kwa mpweya wamlengalenga chifukwa cha radiation kuchokera ku nyenyezi yolandirayo. Amati mapulaneti akabadwa, ambiri, amakhala akulu ndipo pang'onopang'ono amataya kukula, kudwala kozizira komanso kutaya mpweya.

Makhalidwe a Exoplanet 'DS Tuc Ab'.

Ili pamtunda wa kuwala kwa zaka 150 kuchokera pa Dziko Lapansi. Ili ndi masiku awiri ndipo njira yake yozungulira imazungulira nyenyezi yake yayikulu m'masiku 8 okha. Kukula kwake ndikokulirapo kasanu ndi kawiri kuposa kwapadziko lapansi, kofanana ndi Saturn ndi Neptune, ndipo atha kukhala ndi mawonekedwe ofanana ndi awa.

Tiyenera kudziwa kuti mapulaneti amatha kutenga mamiliyoni ngakhale zaka mabiliyoni ambiri kuti afike pokhwima. Chifukwa chake cholinga cha ochita kafukufuku ndikusaka mapulaneti ozungulira nyenyezi zazing'ono kuti adziwe ndikumvetsetsa kusinthika kwawo.

Ndemanga za Elisabeth newton anali:

TESS ndi satelayiti yomwe idakhazikitsidwa pa Epulo 18, 2018, idzapatsidwa ntchito yowunika nyenyezi zopitilira 200.000 kuzungulira dzuwa pofunafuna ma exoplanet, kuphatikiza omwe atha kuthandiza moyo.

Gulu la Newton likuyembekeza kumvetsetsa kuthawa kwamlengalenga ndikusintha kwamlengalenga, zonse zomwe zitha kuneneratu zamtsogolo za exoplanet mzaka zingapo zikubwerazi, komanso momwe izi zingakhudzire mapulaneti ena.
