NGC 1087 ist eine Balken-Spiralgalaxie mit hoher Sternentstehungsrate vom Hubble-Typ SBc im Sternbild Walfisch südlich der Ekliptik. Sie ist rund 68 Millionen Lichtjahre von der Milchstraße entfernt und hat einen Durchmesser von etwa 80.000 Lichtjahren. Das Objekt ist ein enger Nachbar von Messier 77, physisch gehören sie derselben Galaxiengruppe an.[3]
Im selben Himmelsareal befinden sich u. a. die Galaxien NGC 1090, NGC 1094, NGC 1104, IC 1856.
Die Typ-II-Supernova SN 1995V wurde hier beobachtet.[4]
Das Objekt wurde am 9. Oktober 1785 vom deutsch-britischen Astronomen Wilhelm Herschel entdeckt.[5]
Abbildungen
Beobachtungen mit dem Very Large Telescope und dem daran angeschlossenen MUSE-Instrument, sowie mit dem Radiotelskopverbund Atacama Large Millimeter/submillimeter Array zeigen die Galaxie in verschiedenen Spektralbereichen und spiegeln so unterschiedliche Strukturen wider.

The NGC 1087 galaxy as seen with ALMA
This image of the nearby galaxy NGC 1087, taken with the Atacama Large Millimeter/submillimeter Array (ALMA), in which ESO is a partner, shows the distribution of cold clouds of molecular gas, which provide the raw material from which stars form.
NGC 1087 is a spiral galaxy located approximately 80 million light-years from Earth in the constellation of Cetus.
The images were taken as part of the Physics at High Angular resolution in Nearby GalaxieS (PHANGS) project, which is making high-resolution observations of nearby galaxies with telescopes operating across the electromagnetic spectrum.

Warm gas clouds and stars in NGC 1087 mapped with MUSE on ESO’s VLT
This image of the nearby galaxy NGC 1087 was taken with the Multi-Unit Spectroscopic Explorer (MUSE) on ESO’s Very Large Telescope (VLT). The bright reddish glows map warm clouds of hydrogen (Hα), marking the presence of newly born stars, while the bluish regions (a combination of green, red and infrared filters) reveal the distribution of slightly older stars.

NGC 1087 as seen with MUSE on ESO’s VLT at several wavelengths of light
This image, taken with the Multi-Unit Spectroscopic Explorer (MUSE) on ESO’s Very Large Telescope (VLT), shows the nearby galaxy NGC 1087. NGC 1087 is a spiral galaxy located approximately 80 million light-years from Earth in the constellation of Cetus. The image is a combination of observations conducted at different wavelengths of light to map stellar populations and warm gas. The golden glows mainly correspond to clouds of ionised hydrogen, oxygen and sulphur gas, marking the presence of newly born stars, while the bluish regions in the background reveal the distribution of slightly older stars.

NGC 1087 as seen with the VLT and ALMA at several wavelengths of light
This image of the nearby galaxy NGC 1087 was obtained by combining observations taken with the Multi-Unit Spectroscopic Explorer (MUSE) on ESO’s Very Large Telescope (VLT) and with the Atacama Large Millimeter/submillimeter Array (ALMA), in which ESO is a partner. NGC 1087 is a spiral galaxy located approximately 80 million light-years from Earth in the constellation Cetus. The image is a combination of observations conducted at different wavelengths of light to map stellar populations and gas. ALMA’s observations are represented in brownish-orange tones and highlight the clouds of cold molecular gas that provide the raw material from which stars form. The MUSE data show up mainly in gold and blue. The bright golden glows map warm clouds of mainly ionised hydrogen, oxygen and sulphur gas, marking the presence of newly born stars, while the bluish regions reveal the distribution of slightly older stars.
