'''ब्ल्याक होल''' [[अन्तरिक्ष]]मा भएको क्षेत्र हो जहाँ भएको अत्याधिक [[गुरुत्व बल]]का कारण प्रकाश पनि बाहिरिन सक्दैन । [[सामान्य सापेक्षता]]को सिद्धन्त अनुसार अन्तरिक्षमा रहेको उच्च [[घनत्व]] भएको [[पिण्ड]]बाट ब्ल्याक होलको निर्माण हुन्छ । ब्ल्याक होलको वरिपरि गणितीय तथ्यहरूको आधारमा परिभाषित गरिएको काल्पनिक सतह हुन्छ जसलाई घटना क्षितिज (Event Horizon) भनिन्छ । यो क्षेत्रमा पुगेको कुनैपनि वस्तु बाहिर आउन सक्दैन त्यसैले यो क्षेत्रलाई अन्तरिक्ष वैज्ञानिकहरूले '''Point of no return''' को संज्ञा दिएकाछन ।
 
It is called "black" because it absorbs all the light that hits it, reflecting nothing, just like a perfect [[black body]] in [[thermodynamics]].[[Quantum mechanics]] predicts that black holes also emit [[Hawking radiation|radiation]] like a black body with a finite [[temperature]]. This temperature decreases with the mass of the black hole, making it difficult to observe this radiation for black holes of stellar mass.
 
Despite its invisible interior, a black hole can be observed through its interaction with other [[matter]]. A black hole can be inferred by tracking the movement of a group of [[star]]s that orbit a region in space. Alternatively, when gas falls into a [[stellar black hole]] from a [[binary star|companion star]], the gas spirals inward, heating to very high temperatures and emitting large amounts of [[radiation]] that can be detected from earthbound and Earth-orbiting [[telescope]]s.
 
Astronomers have identified numerous stellar black hole candidates, and have also found evidence of [[supermassive black hole]]s at the center of [[galaxy|galaxies]]. In 1998, astronomers found compelling evidence that a supermassive black hole of more than 2 million [[solar mass]]es is located near the [[Sagittarius A*]] region in the center of the [[Milky Way]] galaxy. More recent results using additional data indicate that the supermassive black hole is more than 4 million solar masses.
