A colorful image resembling a cosmic version of an undersea world teeming with stars is being released to commemorate the Hubble Space Telescope’s 30 years of viewing the wonders of space. In the Hubble portrait, the giant red nebula (NGC 2014) and its smaller blue neighbor (NGC 2020) are part of a vast star-forming region in the Large Magellanic Cloud, a satellite galaxy of the Milky Way, located 163,000 light-years away. The image is nicknamed the “Cosmic Reef,” because NGC 2014 resembles part of a coral reef floating in a vast sea of stars. Some of the stars in NGC 2014 are monsters. The nebula’s sparkling centerpiece is a grouping of bright, hefty stars, each 10 to 20 times more massive than our Sun. The seemingly isolated blue nebula at lower left (NGC 2020) has been created by a solitary mammoth star 200,000 times brighter than our Sun. The blue gas was ejected by the star through a series of eruptive events during which it lost part of its outer envelope of material.

ハッブル宇宙望遠鏡が30年間宇宙の驚きに満ちた観測を続けてきた30周年記念として、星が満ち溢れた海底のようなカラフルな宇宙の画像を掲載しました。このハッブルの画像にある巨大な赤い星雲(NGC 2014)とその隣にある小さい青色の星雲(NGC 2020)は、163,000光年先に位置する天の川銀河である大マゼラン星雲の広大な星形成領域の一部です。NGC 2014は広大な星の海に浮かぶサンゴ礁の一部に似ているため「コズミックリーフ」というニックネームで呼ばれています。 NGC 2014の星のいくつかは巨大な星です。星雲のきらめく中心にあるのは、太陽の10倍から20倍の大きさの明るく重い星の集まりです。左下(NGC 2020)で孤立しているように見える青い星雲は、太陽よりも200,000倍明るい単独の超巨大な星でできています。青いガスは一連の爆発により星から放出され、その間に表面の一部が失われました。


Hubble Marks 30 Years in Space With Tapestry of Blazing Starbirth

NASA is celebrating the Hubble Space Telescope’s 30 years of unlocking the beauty and mystery of space by unveiling a stunning new portrait of a firestorm of starbirth in a neighboring galaxy.

Thirty years ago, on April 24, 1990, Hubble was carried aloft from NASA’s Kennedy Space Center in Florida aboard the space shuttle Discovery, along with a five-astronaut crew. Deployed into Earth orbit a day later, the telescope opened a new eye onto the cosmos that has been transformative for our civilization.

30年前の1990年4月24日、ハッブルは5人の宇宙飛行士と共に、フロリダ州にあるNASAのケネディ宇宙センターからスペースシャトルディスカバリー号に搭載されて宇宙中に運ばれました。 1日後に地球の軌道に配置された望遠鏡は、私たちの文明に変革をもたらしてきた宇宙に向かって、新たな目を開けました。

Hubble is revolutionizing modern astronomy, not only for scientists, but also by taking the public on a wondrous journey of exploration and discovery. Hubble’s never-ending, breathtaking celestial snapshots provide a visual shorthand for Hubble’s top scientific achievements. Unlike any space telescope before it, Hubble made astronomy relevant, engaging and accessible for people of all ages. The space telescope’s iconic imagery has redefined our view of the universe and our place in time and space.


“Hubble has given us stunning insights about the universe, from nearby planets to the farthest galaxies we have seen so far,” said Thomas Zurbuchen, associate administrator for science at NASA Headquarters in Washington, D.C. “It was revolutionary to launch such a large telescope 30 years ago, and this astronomy powerhouse is still delivering revolutionary science today. Its spectacular images have captured the imagination for decades, and will continue to inspire humanity for years to come.”

ワシントンDCにあるNASA本部の科学担当副管理者であるトマス・ザブシェンは、次のように述べています。「このような大きな望遠鏡を打ち上げることは革命的でした。 30年前に天文学の大国であったアメリカ合衆国は、今でも革新的な科学を提供し続けています。そこで何十年にもわたって撮影された壮大な画像の数々は、今後も人類を宇宙への関心を突き動かし続けます。」

Unencumbered by Earth’s blurring atmosphere, the space observatory unveils the universe in unprecedented crystal-clear sharpness across a broad range of wavelengths, from ultraviolet to near-infrared light.


On April 24, 2020, the Hubble Space Telescope celebrates its 30th year in orbit by premiering a never-before-seen view of two beautiful nebulas named NGC 2020 and NGC 2014. Hubble’s senior project scientist, Dr. Jennifer Wiseman, takes us on a tour of this stunning new image, describes the telescope’s current health, and summarizes some of Hubble’s contributions to astronomy during its 30-year career.

Hubble’s top accomplishments include measuring the expansion and acceleration rate of the universe; finding that black holes are common among galaxies; characterizing the atmospheres of planets around other stars; monitoring weather changes on planets across our solar system; and looking back in time across 97% of the universe to chronicle the birth and evolution of stars and galaxies.


Hubble has yielded to date 1.4 million observations and provided data that astronomers around the world have used to write more than 17,000 peer-reviewed scientific publications, making it the most prolific space observatory in history. Its archival data alone will fuel future astronomy research for generations to come.


Hubble’s longevity can be attributed to five space shuttle servicing missions, from 1993 to 2009, in which astronauts upgraded the telescope with advanced instruments, new electronics and on-orbit repairs. The venerable observatory, with its suite of cameras and other instruments, is expected to stay operational through the 2020s, in synergy with the upcoming James Webb Space Telescope.


The Hubble Space Telescope is a project of international cooperation between NASA and ESA (the European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope. The Space Telescope Science Institute (STScI) in Baltimore conducts Hubble science operations. STScI is operated for NASA by the Association of Universities for Research in Astronomy in Washington, D.C.
