V\u00f5ib-olla olete kuulnud tumeainest, mis on v\u00e4ga salap\u00e4rane ja mida teadlased pole veel avastanud. Kuid ka tavaline aine, millest koosnevad meile tuttavad asjad \u2013 t\u00e4hed, planeedid ja k\u00f5ik, mida me n\u00e4eme, puudutame v\u00f5i nuusutame \u2013, v\u00f5ib olla salap\u00e4rane! L\u00e4hedal asuvaid galaktikaid uurides oleme avastanud, et m\u00f5nes neist on ainet kolm korda v\u00e4hem, kui me ootaksime. Meie enda galaktikas \u2013 Linnutees \u2013 on ainet v\u00e4hem kui pool sellest, mis seal olema peaks!

Halo on galaktikaid \u00fcmbritsev kuuma gaasi piirkond. Haloid on raske vaadelda ning astronoomid suudavad tavaliselt vaid neisse piiluda, ilma et n\u00e4eksid v\u00e4ga kaugele.
