A ｂlack hole ｉｓ ａ place in ｓpaｃe where gｒavitｙ pulls so ｍuch that eｖeｎ liｇht caｎnｏｔ ｇet out. Ｔhe gravity is so ｓtrong beｃａuse ｍatｔer has beｅn squeezeｄ ｉnｔo a tiny spaｃｅ. Tｈis caｎ haｐpen when a sｔaｒ is ｄyinｇ．
Ｂecａuse ｎｏ liｇht can get out, pｅoｐｌe ｃａn't seｅ blａｃk holｅs. Sｐace tｅleｓcopｅs wiｔh specｉaｌ toｏls can hｅlp find bｌａｃｋ hｏlｅs. The spｅcial tｏols caｎ ｓee ｈoｗ staｒs ｔhat arｅ veｒy ｃlｏse ｔo ｂｌaｃk holeｓ ａｃｔ dｉｆfeｒeｎｔly fｒom otｈer ones.
Bｌack holes can be big or smalｌ. Ｓｃientiｓts thｉnk the sｍallest black ｈoｌｅｓ aｒｅ as sｍaｌl as just oｎｅ atom． Thｅｓe ｂｌack holｅs aｒe ｖｅｒy tｉny buｔ ｈaｖe ｔｈe ｍａsｓ of ａ large ｍountain. Maｓs iｓ the aｍount ｏｆ ｍａtｔer， or “ｓｔａff”, ｉn ａn oｂject.
Anoｔher kind of blacｋ ｈole is called “steｌｌar”（星球黑洞). Its mass can bｅ ｕｐ ｔｏ 20 timｅs morｅ tｈaｎ thｅ mass of the ｓun． Theｒe ｍay be many stellａｒ maｓs ｂlack holｅs in Eaｒtｈ's galaxｙ. Ｅarth's gａlaxy is ｃａllｅd the Ｍilky Way.
The largest blａck ｈoｌes ａrｅ cａlｌed “superｍaｓｓiｖe”（超大质量黑洞). These blａck ｈoles ｈavｅ maｓses thaｔ are more thａn one miｌlion suns together. Scientiｓts ｈave founｄ proof that eveｒy lａrge gaｌａxy contaiｎs ａ ｓuｐｅrmaｓsiｖe ｂlａck hoｌe aｔ its center． Ｔhe suｐerｍaｓsive ｂlａcｋ ｈｏle at the ｃｅnｔer ｏf ｔhｅ Milｋy Waｙ gａｌaxy haｓ ａ mass equａl ｔo ａbｏuｔ foｕｒ ｍillion ｓunｓ and ｗoｕlｄ fiｔ ｉnｓidｅ a verｙ larｇe bａll tｈaｔ coulｄ hoｌd ａ fｅw miｌliｏn Earｔhs.

When ｔhis hａppｅｎs, ｉt ｅxpｌoｄed part oｆ ｔhe ｓtar iｎｔo space． Ｓｃientiｓts thinｋ supermaｓsｉｖｅ black hｏles wｅre made at tｈｅ same ｔime as thｅ galaxｙ thｅy are in.
A ｂlａck hoｌｅ cａn not bｅ ｓｅen becaｕse strong ｇrａvity pｕlｌｓ ａｌl of tｈe lｉght iｎto the midｄｌｅ of ｔhe blacｋ hole． But scｉentiｓts cａn see how ｔhe ｓtroｎg ｇrａvｉｔy ａffects tｈe stars and ｇａs arouｎd ｔhe black hｏle． Ｓcientisｔｓ caｎ ｓｔｕdｙ starｓ to ｆinｄ out if ｔhey ａｒe fｌｙiｎｇ ａrouｎｄ， or orbｉtｉng a black hoｌe.
Whｅn a bｌaｃｋ holｅ and ａ ｓtａr are clｏse ｔoｇetheｒ， hｉgｈ-ｅnergy liｇht ｉs made. Ｔhｉｓ kind of liｇht cannot be seｅn ｗith ｈumａn eyｅs. Ｓｃｉentisｔs use ｓatelliｔes and ｔelescopes in spaｃe tｏ see the high－enｅｒgy lｉght．
