Pan of Star AG Carinae | Hubble

This video showcases a pan of star AG Carinae from the NASA/European Space Agency Hubble Space Telescope.

The star is waging a tug-of-war between gravity and radiation to avoid self-destruction. AG Carinae is surrounded by an expanding shell of gas and dust—a nebula. The nebula is about five light-years wide, which equals the distance from here to our nearest star, Alpha Centauri.

Snapshot of a Shedding Star: AG Carinae | Hubble

Snapshot of a Shedding Star: AG Carinae | Hubble


In this Hubble image, the strikingly luminous star AG Carinae—otherwise known as HD 94910 — takes center stage. Found within the constellation of Carina in the southern sky, AG Carinae lies 20,000 light-years away, nestled in the Milky Way.

AG Carinae is classified as a Luminous Blue Variable. These rare objects are massive evolved stars that will one day become Wolf-Rayet Stars—a class of stars that are tens of thousands to several million times as luminous as the Sun. They have evolved from main sequence stars that were twenty times the mass of the Sun.

Stars like AG Carinae lose their mass at a phenomenal rate. This loss of mass is due to powerful stellar winds with speeds of up to 7 million km/hour. These powerful winds are also responsible for the shroud of material visible in this image. The winds exert enormous pressure on the clouds of interstellar material expelled by the star and force them into this shape.

Despite HD 94910’s intense luminosity, it is not visible with the naked eye as much of its output is in the ultraviolet.

This image was taken with the Wide Field and Planetary Camera 2 (WFPC2), that was installed on Hubble during the Shuttle mission STS-61 and was Hubble’s workhorse for many years. It is worth noting that the bright glare at the center of the image is not the star itself. The star is tiny at this scale and hidden within the saturated region. The white cross is also not an astronomical phenomenon but rather an effect of the telescope.

A Wanderer Dancing the Dance of Stars and Space | Hubble

A Wanderer Dancing the Dance of Stars and Space | Hubble


The NASA/European Space Agency Hubble Space Telescope provided a spectacular image of the bright star-forming ring that surrounds the heart of the barred spiral galaxy NGC 1097. In this image, the larger-scale structure of the galaxy is barely visible—its comparatively dim spiral arms, which surround its heart in a loose embrace, reach out beyond the edges of this frame.

This face-on galaxy, lying about 45 million light-years away from Earth in the southern constellation of Fornax (The Furnace), is particularly attractive for astronomers. NGC 1097 is a Seyfert galaxy. Lurking at the very center of the galaxy, a supermassive black hole 100 million times the mass of our Sun is gradually sucking in the matter around it. The area immediately around the black hole shines powerfully with radiation coming from the material falling in.

The distinctive ring around the black hole is bursting with new star formation due to an inflow of material toward the central bar of the galaxy. These star-forming regions are glowing brightly thanks to emission from clouds of ionized hydrogen. The ring is around 5,000 light-years across, although the spiral arms of the galaxy extend tens of thousands of light-years beyond it.

NGC 1097 is also pretty exciting for supernova hunters. The galaxy experienced three supernovae (the violent deaths of high-mass stars) in the 11-year span between 1992 and 2003. This is definitely a galaxy worth checking on a regular basis.

However, what it is really exciting about NGC 1097 is that it is not wandering alone through space. It has two small galaxy companions, which dance “the dance of stars and the dance of space” like the gracious dancer of the famous poem The Dancer by Khalil Gibran.

The satellite galaxies are NGC 1097A, an elliptical galaxy orbiting 42,000 light-years from the center of NGC 1097 and a small dwarf galaxy named NGC 1097B. Both galaxies are located out beyond the frames of this image and they cannot be seen. Astronomers have indications that NGC 1097 and NGC 1097A have interacted in the past.

This picture was taken with Hubble’s Advanced Camera for Surveys using visual and infrared filters.

Galaxy NGC 1275: Multi-wavelength Composite View | Hubble

Galaxy NGC 1275: Multi-wavelength Composite View | Hubble


The behemoth galaxy NGC 1275, also known as Perseus A, lies at the center of Perseus Galaxy Cluster. By combining multi-wavelength images into this single composite, the dynamics of the galaxy become visible. Detail and structure from optical, radio, and X-ray wavelengths have been combined for an aesthetically pleasing image which shows the violent events in the galaxy's heart. NGC 1275 is an active galaxy well-known for its radio source (Perseus A) and is a strong emitter of X-rays due to the presence of the supermassive black hole in its center.

Hubble data from the Advanced Camera for Surveys covers visible-light wavelengths and is shown in the red, green and blue. Radio data from NRAO's Very Large Array at 0.91 m was also used. In this composite image, dust lanes, star-forming regions, hydrogen filaments, foreground stars, and background galaxies are contributions from the Hubble optical data. The X-ray data contributes to the soft but violet shells around the outside of the centre. The pinkish lobes toward the center of the galaxy are from radio emission. The radio jets from the black hole fill the X-ray cavities. Chandra data from the ACIS covers X-ray wavelengths from 0.1771 to 4.133 nm (0.3-7 KeV).

Hubblecast 18: The Hubble Space Telescope has solved a long-standing puzzle by resolving giant but delicate filaments shaped by a strong magnetic field around the active galaxy NGC 1275. It is the most striking example so far of the influence of the immense tentacles of extragalactic magnetic fields.

A Delicate Extragalactic Web: Galaxy NGC 1275 | Hubble


The dusty web of filaments seen in this fulldome clip have been teased out of their host galaxy NGC 1275 by rising "bubbles" of plasma produced by the galaxy's central black hole. Their delicate forms should have collapsed long ago, but are thought to be preserved by a weak magnetic field around them.

Magnetic Monster: Galaxy NGC 1275 | Hubble

Magnetic Monster: Galaxy NGC 1275 | Hubble

This stunning image of NGC 1275 was taken using the NASA/European Space Agency Hubble Space Telescope's Advanced Camera for Surveys in July and August 2006. It provides amazing detail and resolution of the fragile filamentary structures, which show up as a reddish lacy structure surrounding the central bright galaxy NGC 1275. These filaments are cool despite being surrounded by gas that is around 55 million degrees Celsius hot. They are suspended in a magnetic field which maintains their structure and demonstrates how energy from the central black hole is transferred to the surrounding gas.

Distance: 250 million light years

By observing the filamentary structure, astronomers were, for the first time, able to estimate the magnetic field's strength. Using this information they demonstrated how the extragalactic magnetic fields have maintained the structure of the filaments against collapse caused by either gravitational forces or the violence of the surrounding cluster during their 100-million-year lifetime.

This is the first time astronomers have been able to differentiate the individual threads making up such filaments to this degree. Astonishingly, they distinguished threads a mere 200 light-years across. By contrast, the filaments seen here can be a gaping 200,000 light-years long. The entire image is approximately 260,000 light-years across.

Also seen in the image are impressive lanes of dust from a separate spiral galaxy. It lies partly in front of the giant elliptical central cluster galaxy and has been completed disrupted by the tidal gravitational forces within the galaxy cluster. Several striking filaments of blue newborn stars are seen crossing the image.
