[漢羅] 超新星炮台 kā 脈動星 J0002 搩出去

是啥物物件會當 kā 中子星 當做炮彈按呢射出去？ 是超新星啦！ 差不多 1 萬年前，tī 銀河系內底 生出 超新星殘骸 CTB 1 ê 超新星，毋若毀滅一粒大質量恆星，而且 kā 新形成 ê 中子星 ê 核心，脈動星，炸掉矣。 這粒脈動星 一秒鐘踅 8.7 擺。 會揣著伊，是利用一款會當下載到家己電腦 ê 軟體 Einstein@Home，連到 踅地球--ê NASA Fermi Gamma-Ray 天文台 資料庫搜揣資料，才發現--ê。 這粒 脈動星 PSR J0002+6216 (簡稱 J0002) 一秒鐘行 1000 公里，早就已經脫離 超新星殘骸 CTB 1，而且伊 ê 速度緊甲 會當離開咱 ê 銀河系。 Tī 這張相片內底，咱會當看著 脈動星 ê 路線拖到超新星殘骸 ê 倒爿下跤遐。 這張影像 是 kā VLA kah DRAO 電波天文台 翕著 ê 電波影像，kah 踅地球 ê NASA IRAS 紅外線 天文台 ê 資料庫影像 鬥做伙，產生 ê 合成影像。 咱已經知影講超新星就敢若是炮台，咱嘛知影 脈動星就敢若是炮彈，毋閣咱猶毋知超新星是按怎 kā 脈動星搩出去--ê。

[English] Supernova Cannon Expels Pulsar J0002

What could shoot out a neutron star like a cannon ball? A supernova. About 10,000 years ago, the supernova that created the nebular remnant CTB 1 not only destroyed a massive star but blasted its newly formed neutron star core -- a pulsar -- out into the Milky Way Galaxy. The pulsar, spinning 8.7 times a second, was discovered using downloadable software Einstein@Home searching through data taken by NASA's orbiting Fermi Gamma-Ray Observatory. Traveling over 1,000 kilometers per second, the pulsar PSR J0002+6216 (J0002 for short) has already left the supernova remnant CTB 1, and is even fast enough to leave our Galaxy. Pictured, the trail of the pulsar is visible extending to the lower left of the supernova remnant. The featured image is a combination of radio images from the VLA and DRAO radio observatories, as well as data archived from NASA's orbiting IRAS infrared observatory. It is well known that supernovas can act as cannons, and even that pulsars can act as cannonballs -- what is not known is how supernovas do it.
