New data from the European Gaia space telescope could lead to a downward revision to tally of Earth-like worlds
开普勒任务(Kepler Mission)是 NASA 设计用来发现环绕其他恒星之类地行星的太空望远镜,在绕行太阳的轨道上利用凌日法观测 10 万颗恒星,对各种不同光谱类型的恒星进行广泛观测,以确定有多少类似地球的行星或大行星存在、邻近适居带,自 2009 年发射以来,开普勒望远镜已经帮助科学家确认了数以千计的系外行星。 其他任务目...
NASA的官方网站在发布这一消息时,使用的标题是“NASA's Kepler Mission Confirms Its First Planet in Habitable Zone of Sun-like Star”,正确地翻译成中文应该是“NASA开普勒计划证实它的首颗位于类太阳恒星宜居带中的行星”。这里的“首颗”,指的只是开普勒计划证实的首颗,而非天文学家发现的首...
美国太空种署NASA的克普勒任务(Kepler Mission)太空望远镜自2009年发射,到2年前用尽能源,期间发现并确认了一颗距离地球3百光年的行星,令人振奋的是它的气温条件及体积与地球非常相像,科学家们决定以Kepler-1…
根据第一段的In July, 2015, NASA's Kepler mission has confirmed the first near-Earth-size planet in the "habitable zone" around a sun-like star.(2015年7月,美国航天总局的开普勒任务在一颗类似太阳的恒星周围的“宜居带”发现了一颗接近地球大小的行星。)和第三段的"On the 20th anniversary year of...
MJ: Mike, what information has the Kepler mission recently delivered to the NASA Exoplanet Archive? MH: The Kepler mission has just opened the Q1-Q12 activity table at the NASA Exoplanet Archive and delivered a majority of the Kepler Objects of Interest (KOIs) found by searching the data fr...
NASA's Kepler Mission has discovered the first near-Earth-size planet orbiting in the habitable zone of a star very similar to our Sun. NASA的开普特太空望远镜发现了首颗与地球大小近似并绕一颗类似太阳的恒星运行的行星。该行星位于其恒星周围的适居地带。 Located about 1,400 light-years from Earth ...

相对来说,开普勒任务(Kepler mission)搜寻从地球到天鹅座之间距离数千万光年内的系外行星,而TESS将在我们的太阳系周围数百光年以内搜寻系外行星。 TESS将通过将天空分割成26个不同的部分即测量意义上的瓦片(tiles)进行勘测。该航天器的强大的相机将在每一区持续观测27天,每两分钟测量一次从最亮的目标发出的可见光...
