A Pillar of Creation within the Eagle Nebula

Eerie, dramatic pictures from the Hubble telescope show newborn stars emerging from “eggs”— not the barnyard variety— but rather, dense, compact pockets of interstellar gas called evaporating gaseous globules (EGGs). Hubble found the “EGGs,” appropriately enough, in the Eagle nebula (M18), a nearby star-forming region 7,000 light-years from Earth in the constellation Serpens. (Read More)

Doradus Nebula

A panoramic view of a vast, sculpted area of gas and dust where thousands of stars are being born has been captured by NASA’s Hubble Space Telescope.

The photo offers an unprecedented, detailed view of the entire inner region of the fertile, star-forming 30 Doradus Nebula. The mosaic picture shows that ultraviolet radiation and high-speed material unleashed by the stars in the cluster, called R136 (the large blue blob left of center), are weaving a tapestry of creation and destruction, triggering the collapse of looming gas and dust clouds and forming pillar-like structures that incubate newborn stars.

The 30 Doradus Nebula is in the Large Magellanic Cloud, a satellite galaxy of the Milky Way located 170,000 light-years from Earth. Nebulas like 30 Doradus are signposts of recent star birth. High-energy ultraviolet radiation from young, hot, massive stars in R136 causes surrounding gaseous material to glow. Previous Hubble telescope observations showed that R136 contains several dozen of the most massive stars known, each about 100 times the mass of the Sun and about 10 times as hot. These stellar behemoths formed about 2 million years ago.

Galaxies spiralling around Leo

Shown here is a spiral galaxy known as NGC 3455, which lies some 65 million light-years away from us in the constellation of Leo (The Lion).

Galaxies are classified into different types according to their structure and appearance. This classification system is known as the Hubble Sequence, named after its creator Edwin Hubble.

In this sequence, NGC 3455 is known as a type SB galaxy — a barred spiral. Barred spiral galaxies account for approximately two thirds of all spirals. Galaxies of this type appear to have a bar of stars slicing through the bulge of stars at their centre. The SB classification is further sub-divided by the appearance of a galaxy’s pinwheeling spiral arms; SBa types have more tightly wound arms, whereas SBc types have looser ones. SBb types, such as NGC 3455, lie in between.

NGC 3455 is part of a pair of galaxies — its partner, NGC 3454, lies out of frame. This cosmic duo belong to a group known as the NGC 3370 group, which is in turn one of the Leo II groups, a large collection of galaxies scattered some 30 million light-years to the right of the Virgo cluster.

Rockwarbler (Origma solitaria)

Also known as the “Origma”, the rockwarbler is a species of Australasian warbler (Acanthizidae) that is the sole member of the genus Origma. Rockwarblers are endemic to the central eastern New South Wales in Australia. True to their common names Rockwarblers are typically seen foraging for insects with in woodlands with sandstone or limestone.

Lebrunia danae
…is an unusual species of Aliciid sea anemone that occurs in the Caribbean Sea and Gulf of Mexico. Like many sea anemones L. danae typically inhabits reef environments at depths ranging from 2-60 m. Unlike other sea anemones L. danae's tentacles are hidden by a ring of six branching pseudotentacles around the oral disc. When L. danae comes in contact with a prey item to pseudotentacles will retract and the true tentacles (which are armed with nematoctsts) will take the prey and move it towards the mouth.

Pygmy Falcon (Polihierax semitorquatus)

Also known as the African Pygmy Falcon, P. semitorquatus is a small species of falcon, that occurs in eastern and southern Africa. The population in eastern Africa (P. s. castanotus) occurs from Sudan to Somalia south to Uganda and Tanzania. The population in southern Africa (P. s. semitorquatus) occurs from Angola to South Africa.

True to its common name P. semitorquatus is very small at only 19-20 cm long, making it the smallest raptor in Africa. Pygmy falcons typically inhabit dry bush habitats and will feed on insects, small mammals, birds, and reptiles. Pygmy falcons will usually in the nests of weavers, and even though they feed on bird will rarely go after their weaver neighbors.
