太陽系形成時の残滓(ざんし)である小惑星がただの乾いた岩ではないことを証明する発見となった
It was discovered to prove that the asteroid, which is the residue when the solar system is formed, is not just a dry rock.

天文学者の見方では、水などが初期の地球に運ばれたのは小惑星の衝突が要因だった可能性がある
According to the astronomer`s point of view, it is possible that water and the like were transported to the early Earth due to the collision of asteroids.

新たな研究によると、小惑星に水が存在する証拠が見つかったことで、こうした理論の裏付けになる可能性があるという
According to a new study, the found that evidence of water on asteroids could support such a theory.

この二つの小惑星は火星と木星の軌道に挟まれた小惑星帯(メインベルト)にあり、どちらも太陽から約3億5700万キロ以上離れている
These two asteroids are located in the asteroid belts (main belts) between Mars and Jupiter, both of which are about 357 million km away from the sun.

研究結果は12日、専門誌プラネタリー・サイエンス・ジャーナルに発表された
論文の筆頭著者を務めた米サウスウェスト研究所のアニシア・アレドンド氏によると、小惑星の調査にSOFIAを使用するという発想は、SOFIAで月面に水の証拠が見つかったことをきっかけに生まれた
イリスとマッサリアでは以前にも、論文の共著者が別の望遠鏡を使って水和反応の証拠を発見していた
ただ、水分子がこの水和反応を引き起こしたのか、それとも水酸基などが引き起こしたのかは研究者にも分かっていなかったという
アレドンド氏は「SOFIAを使った新たな観測の結果、彼らが見たものが水だったことが確定した」と指摘している
