Narrative:

First officer was flying the approach and landing at night under VMC conditions. We were on short final with clearance to land on a stabilized approach. At about 150 ft, we noticed the VASI lights being blocked or going on/off. At about 100 ft, we realized that there was a darkened aircraft moving across the approach end of the runway directly in our landing path. It was apparent that the intruding aircraft would still be on, or very near, the landing zone as we would land and we started a go around. At that same time, tower called for us to go around. We conducted a go around and proceeded to conduct an approach and landing to runway 26 at dia. After landing, ground control stated to us that aircraft Y, which caused the go around, had been experiencing hot brakes and that the tower wasn't aware of this, but that caused them to be slow at clearing the runway. I stated that their aircraft was completely dark and we only saw it as our landing lights lit it up.

Title: B737 LNDG DEN EXPERIENCED GAR, ACFT SLOW EXITING RWY.

Narrative: FO WAS FLYING THE APCH AND LNDG AT NIGHT UNDER VMC CONDITIONS. WE WERE ON SHORT FINAL WITH CLRNC TO LAND ON A STABILIZED APCH. AT ABOUT 150 FT, WE NOTICED THE VASI LIGHTS BEING BLOCKED OR GOING ON/OFF. AT ABOUT 100 FT, WE REALIZED THAT THERE WAS A DARKENED ACFT MOVING ACROSS THE APCH END OF THE RWY DIRECTLY IN OUR LNDG PATH. IT WAS APPARENT THAT THE INTRUDING ACFT WOULD STILL BE ON, OR VERY NEAR, THE LNDG ZONE AS WE WOULD LAND AND WE STARTED A GAR. AT THAT SAME TIME, TWR CALLED FOR US TO GO AROUND. WE CONDUCTED A GAR AND PROCEEDED TO CONDUCT AN APCH AND LNDG TO RWY 26 AT DIA. AFTER LNDG, GND CTL STATED TO US THAT ACFT Y, WHICH CAUSED THE GAR, HAD BEEN EXPERIENCING HOT BRAKES AND THAT THE TWR WASN'T AWARE OF THIS, BUT THAT CAUSED THEM TO BE SLOW AT CLRING THE RWY. I STATED THAT THEIR ACFT WAS COMPLETELY DARK AND WE ONLY SAW IT AS OUR LNDG LIGHTS LIT IT UP.
