He is considered one of the founding figures of radio astronomy.
The first detection of radio waves from an astronomical object was in 1932, when Karl Jansky at Bell Telephone Laboratories observed radiation coming from the Milky Way.

In 1928 he joined the Bell Telephone Laboratories site in Holmdel, New Jersey. The original site of Jansky's antenna (40.36514°N, -74.16358°W) at what is now the vacant Bell Labs Holmdel Complex at 101 Crawfords Corner Road, Holmdel, New Jersey, was determined by Tony Tyson and Robert Wilson of Lucent Technologies (the successor of Bell Telephone Laboratories) in 1998, and a monument and plaque were placed there to honor the achievement.
The earliest work on radio astronomy was conducted by Bell Labs engineer Karl Guthe Jansky in 1931 in Holmdel.

In 1931, a foundation for radio astronomy was laid by Karl Jansky during his work investigating the origins of static on long-distance shortwave communications.

Karl's brother Cyril Jansky Jr., who was ten years older, helped build some of the earliest radio transmitters in the country, including 9XM in Wisconsin (now WHA of Wisconsin Public Radio) and 9XI in Minnesota (now KUOM).
These operations were under the oversight of electrical engineering professor C. M. Jansky, Jr., the older brother of Karl Jansky.

Grote Reber

Reber, Grote
Two men who learned of Jansky's 1933 discovery were of great influence on the later development of the new study of radio astronomy: one was Grote Reber, a radio engineer who singlehandedly built a radio telescope in his Illinois back yard in 1937 and did the first systematic survey of astronomical radio waves.
He was instrumental in investigating and extending Karl Jansky's pioneering work, and conducted the first sky survey in the radio frequencies.

In honor of Jansky, the unit used by radio astronomers for the strength (or flux density) of radio sources is the jansky (1 Jy = 10 −26 W m −2 Hz −1 ).

National Radio Astronomy Observatory

SocorroNRAOJansky Lectureship
The NRAO postdoctoral fellowship program is named after Karl Jansky.
The observatory contains several other telescopes, among them the 140 ft telescope that utilizes an equatorial mount uncommon for radio telescopes, three 85 ft telescopes forming the Green Bank Interferometer, a 40 ft telescope used by school groups and organizations for small scale research, a fixed radio 'horn' built to observe the radio source Cassiopeia A, as well as a reproduction of the original antenna built by Karl Jansky while he worked for Bell Labs to detect the interference that was discovered to be previously unknown natural radio waves emitted by the universe.

Very Large Array

On January 10, 2012, the NRAO announced the Very Large Array (VLA), the radio telescope in Magdalena, New Mexico, would be renamed the Karl G. Jansky Very Large Array in honor of Karl Jansky's contribution to Radio Astronomy.
To reflect this increased capacity, VLA officials asked for input from both the scientific community and the public in coming up with a new name for the array, and in January 2012 it was announced that the array would be renamed the "Karl G. Jansky Very Large Array".

Karl Guthe Jansky invented radio astronomy there, and a monument was placed at the former location (40.36514°N, -74.16358°W) of the antenna almost seventy years later in 1998.
