This NASA/ESA Hubble Space Telescope image reveals the subtle glow of the galaxy named IC 3430, located 45 million light-years from Earth in the constellation Virgo. This dwarf elliptical galaxy is part of the Virgo cluster, a rich collection of galaxies both large and small, many of which are very similar in type to this diminutive galaxy.
Like its larger elliptical cousins, IC 3430 has a smooth, oval shape lacking any recognizable features like arms or bars, and is missing much of the gas needed to form many new stars. Interestingly, IC 3430 does feature a core of hot, massive blue stars —an uncommon sight in elliptical galaxies — that indicates recent star-forming activity. Astronomers think that pressure from the galaxy ploughing through gas within the Virgo cluster ignited what gas IC 3430 had in its core to form the newer stars.
Dwarf galaxies are really just galaxies with fewer stars, usually less than a billion, but that is often enough for them to reproduce, in miniature, the same forms as larger galaxies. There are dwarf elliptical galaxies like IC 3430, dwarf irregular galaxies, dwarf spheroidal galaxies, and even dwarf spiral galaxies!

Johann-Dietrich Wörner, director general of ESA (European Space Agency), speaks at a bi-lateral meeting about NASA’s plans to land humans on the Moon by 2024 and prospective collaboration in human and robotic lunar and Mars exploration activities, at the Space Symposium, Monday, April 8, 2019 in Colorado Springs, Colorado. They also discussed their continued successful cooperation on the International Space Station and the service module for the Orion spacecraft that will take us to the Moon and beyond.

ESA project astronaut Marcus Wandt during training in the USA for his Muninn mission to the International Space Station.
Marcus Wandt from Sweden will travel to the International Space Station on Axiom Mission 3 (Ax-3). He will spend up to 14 days in orbit conducting microgravity research and educational activities.
Marcus is the first of a new generation of European astronauts to fly on a commercial human spaceflight opportunity with Axiom Space. His mission is supported by ESA and the Swedish National Space Agency (SNSA).
Marcus Wandt was selected in November 2022 as a member of the ESA astronaut reserve after a year-long selection process. The 2022 ESA recruitment campaign received over 22 5000 applications from across its Member States.

Measuring the distance to truly remote objects like galaxies, quasars, and galaxy clusters is a crucial task in astrophysics, particularly when it comes to studying the early universe, but it’s a difficult one to complete. We can only measure the distances to a few nearby objects like the Sun, planets, and some nearby stars directly. Beyond that, astronomers need to use various indirect methods; one of the most important examines Type Ia supernovae, and this is where the NASA/ESA Hubble Space Telescope excels.
NGC 3810, the galaxy featured in this image, was the host of a Type Ia supernova in 2022. In early 2023, Hubble focused on this and a number of other galaxies to closely examine recent Type Ia supernovae. Type Ia supernovae are the result of a white dwarf exploding, and their peak brightness is very consistent. This attribute allows astronomers to use Type Ia supernovae to measure distances: we know how bright a Type Ia supernova should be, so we can tell how far away it must be by how dim it appears. One snag with this method is intergalactic dust. Because intergalactic dust blocks some of the supernova’s light, astronomers need to determine how much light the dust reduces to accurately measure the supernova’s brightness and calculate its distance. Hubble’s unique capabilities offer them a clever way of doing this.
Astronomers use Hubble to take images of the same Type Ia supernovae in ultraviolet light, which the dust almost completely blocks out, and in infrared light, which passes through dust nearly unaffected. By carefully noting how much light comes through at each wavelength, astronomers can determine how much dust lies between Hubble and the supernova, letting them confidently calibrate the relationship between a supernova’s brightness and its distance. Hubble’s unique capability to observe in ultraviolet and infrared wavelengths of light in great detail with the same instrument makes it the perfect tool for these types of observations. Indeed, some of the data used to make this beautiful image of NGC 3810 focused on its 2022 supernova. You can see it as a point of light just below the galactic nucleus.
There are many ways to measure cosmic distances, but Type Ia supernovae are one of the most useful and accurate tools because they are so bright. Astronomers must use other methods as well, either as an independent check against other distance measurements, or to measure at much closer or farther distances. One such method, that also works for galaxies, is comparing their rotation speed to their brightness; based on that method, NGC 3810 is about 50 million light-years from Earth.

ESA and the Italian space agency ASI sign an agreement at the Intermediate Ministerial Meeting (IMM18), in Madrid, Spain, to pursue cooperation concerning the future deployment of the novel Fly-Eye telescope to the site of Monte Mufara, Sicily. The high performance Fly-Eye telescope will be used to systematically and regularly survey the sky for the purpose of detecting asteroids approaching Earth and representing a threat of collision with our planet.
ESA’s Ministers in charge of space activities convened at IMM18 at ESA’s European Space Astronomy Centre (ESAC) in Villanueva de la Cañada, on 25 October 2018.
The Intermediate Ministerial Meeting is a milestone on the road to Space19+, ESA’s next Council at ministerial level which will be held in Seville, Spain, in November 2019.
