Hegra is a village and former municipality in Nord-Trøndelag county, Norway. The former municipality encompassed most of the eastern part of the present-day municipality of Stjørdal. The ancient rock carvings (Leirfald), as well as the small border fort Hegra Fortress (formerly known as Ingstadkleven Fort) are both located in Hegra. The fortress withstood the invading German army from 10 April to 5 May 1940, not surrendering before all other Norwegian units in Southern Norway and Mid-Norway had capitulated.
The 0.42-square-kilometre (100-acre) village of Hegra has a population (2013) of 505. The population density of the village is 1,202 inhabitants per square kilometre (3,110/sq mi). Hegra is located about 10 kilometres (6.2 mi) east of Stjørdalshalsen along the Stjørdalselva river and it is therefore a good site for fishing. Hegra has its own grocery store, gas station, kindergarten, school and a local bank. Hegra is also one of the centers for the resurgence of the Dole Gudbrandsdal horse in Norway. The village is served by the unmanned Hegra Station on the Meråker Line. The European route E14 highway also runs through the village, just south of Hegra Church.

HEGRA, which stands for High-Energy-Gamma-Ray Astronomy, was an atmospheric Cherenkov telescope for Gamma-ray astronomy. With its various types of detectors, HEGRA took data between 1987 and 2002, at which point it was dismantled in order to build its successor, MAGIC, at the same site.
It was located at Roque de los Muchachos Observatory on La Palma at a height of 2200 m above sea level. It was operated by an international collaboration of research institutes and universities, such as the Max Planck Institute for Physics in Munich, the Universidad Complutense de Madrid, the German Max Planck Institute for Nuclear Physics, the University of Wuppertal, the IFKKI in Kiel or the University of Hamburg. It consisted of several detector types for observing secondary particles from particle cascades in the atmosphere. The particle cascardes detected by HEGRA were produced by cosmic ray particles in the energy range of 1012eV to 1016eV.
The detectors with the lowest energy threshold were the atmospheric Cherenkov telescopes with "cameras" of photomultiplier tubes. They were sensitive to showers above 1012eV (1 TeV) but had to look towards possible sources and could be operated only during clear, moonless nights. They detected Cherenkov light from relativistic secondary particles in the air showers. The field of view was about 4.6°. There were a total of six of these telescopes in operation. They were dismantled in September 2002.
I got the card, delivers the goods
Fills me with happiness
It's joy for a while 'till the first of the month
Then I'm chasing my tail again
I want a life that's bigger than me
'Cause I'm crushing myself to death
Tell you what I don't need
No heaven sent deity
'Cause I'm an ordinary angel
Winning tiny victories
And though the ordinary angels fly
Their wings weigh heavily
I try to be a daily genius
There's no idea beyond my reach
With all the angels and the geniuses
My company I'm gonna keep
I'm watching the news and I feel my face
Hanging like plasticene
Now I see the plot, I've got the plan
Every move is transparent to me
Profit and power's turning the world
And I'm leaning against the spin
Give me a vision please
And I don't mean heavenly
I am an ordinary angel child
Walking with the daily geniuses
