NGC 4438 is the most curious interacting galaxy in the Virgo Cluster, due to the uncertainty surrounding the energy mechanism that heats the nuclear source; this energy mechanism may be a starburst region, or a black hole-powered active galactic nucleus (AGN). Both hypotheses are currently under investigation by astronomers.

2016年11月16日 · NGC 4435 is a compact barred lenticular galaxy that appears to be almost devoid of dust and gas. The galaxy contains a young population of stars on its central regions.

2000年6月5日 · Known as a peculiar galaxy because of its unusual shape, NGC 4438 is in the Virgo Cluster, 50 million light-years from Earth. Are you a journalist? Subscribe to the ESA/Hubble Media Newsletter.

NGC 4438 is a Spiral Galaxy in the Virgo constellation. NGC 4438 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year. Given its visual magnitude of 10.17, NGC 4438 is visible with the help of a binocular with a 80mm aperture or a small telescope.

The galaxy NGC 4438 belongs to the Hubble class SA (s)0/a (peculiar). The inclination of its disk is unclear; values range between 68° and 85° with respect to the sky plane. This galaxy has a distance median value of 13 Mpc.

During the encounter between NGC4438 and NGC 4435, gravitational tidal forces tugged at the gas and stars on the outer parts of the galaxies. NGC 4438 was damaged in the collision, but the hot gas will probably fall back into the disk of the galaxy in a few hundred million years.

2003年12月12日 · We present results from a 25 ksec CHANDRA ACIS-S observation of galaxies NGC4438 and NGC4435 in the Virgo Cluster. X-ray emission in NGC4438 is observed in a ~700 pc nuclear region, a 2.3 kpc spherical bulge, and a network of filaments extending 4-10 kpc to the W and SW of the galaxy.

The galaxy NGC 4438 belongs to the Hubble class SA (s)0/a (peculiar). The inclination of its disk is unclear; values range between 68° and 85° with respect to the sky plane. This galaxy has a distance median value of 13 Mpc.

2007年6月21日 · We present multi-frequency, radio-continuum and HI observations of NGC4438, the highly-disturbed, active galaxy in the Virgo cluster, with the VLA and the GMRT. High-resolution observations with...

2024年1月14日 · NGC4435 and NGC4438 - posted in Experienced Deep Sky Imaging: The galaxies at the tail of Markariaons Chain. Here is a crop of an image I took a few months ago and found on my ASIAir last night after an imaging session.
