Raspberry space cocktail<\/h2>\n\n

When is a nebula not a nebula? When it\u2019s two nebulae in one <\/p>\n\n

NICHOLAS U MAYALL TELESCOPE, 19 APRIL 2023 <\/strong><\/h4>\n\n

Captured by the Nicholas U Mayall 4-metre Telescope at the Kitt Peak National Observatory in Arizona using its new Mosaic-3 detector, this is LBN 867, the Raspberry Nebula, which lies in the constellation of Orion. Look more closely, though, and you can see that LBN 867 is actually three objects in one: two nebulae and a powerful main sequence star. <\/p>\n\n

This blue-white star, HD 34989, lies at its heart. Surrounding it is the red emission nebula Sh2-263 \u2013 a diffuse region of hydrogen ionised by the heat and light energy coming from the star, and so giving off a reddish glow. Meanwhile, towards the bottom left of the photo, an adjacent cloud of cosmic dust is reflecting that same light, forming the blue reflection nebula vdB 38. <\/p>\n\n

Somewhat confusingly, another celestial object is sometimes called the Raspberry Nebula \u2013 namely the planetary nebula IC 418 in the nearby constellation of Lepus (not seen here). But for sheer majesty, it can\u2019t quite compete with LBN 867\u2019s trio of delights. <\/p>\n\n

IXPE\/CHANDRA X-RAY OBSERVATORY, 10 APRIL 2023<\/strong><\/p>\n\n

Combining data captured by NASA\u2019s Imaging X-ray Polarimetry Explorer (IXPE) satellite and Chandra X-ray Observatory, this image shows the Crab Nebula, a supernova remnant some 6,500 lightyears from Earth that\u2019s also known as Taurus A, M1 or NGC 1952. The nebula was formed by a supernova that was recorded by Chinese astronomers in 1054, and the picture clearly shows the Crab Pulsar that lies at its heart, as well as the turbulent magnetic field that surrounds it. <\/p>\n\n

Eighth wonder <\/h4>\n\n

JAMES WEBB SPACE TELESCOPE, 6 APRIL 2023<\/strong><\/p>\n\n

William Herschel speculated that Uranus may have a ring system way back in the 18th century, but it wasn\u2019t until 1977 that its existence was proven, while our first images of the rings were provided by Voyager 2 in 1986. Those first grainy black and white pictures can\u2019t compare, though, to this stunning new JWST image which shows 11 of the 13 known rings, as well as an area of brightening at the planet\u2019s northern pole, which currently faces the Sun. <\/p>\n\n

A hard rain\u2019s gonna fall <\/h4>\n\n

HUBBLE SPACE TELESCOPE\/CASSINI\/VOYAGER, 30 MARCH 2023<\/strong><\/p>\n\n

You\u2019d expect icy particles falling from space to have a chilling effect, but as this UV image of Saturn shows, that\u2019s not necessarily true. Generated using UV data from the Voyager 1, Voyager 2, Cassini, Hubble and International Ultraviolet Explorer missions, it shows a band of higher UV radiation below Saturn\u2019s rings, denoting higher temperatures \u2013 thought to be caused by particles hitting the upper atmosphere. It\u2019s hoped this discovery may help astronomers identify which exoplanets also have rings. <\/p>\n\n

Head-on collision <\/h4>\n\n

GEMINI NORTH, 29 MARCH 2023<\/strong><\/p>\n\n

This image captured by the Gemini North telescope shows the aftermath of a head-on collision between the two Taffy Galaxies, UGC 12914 (left) and UGC 12915 (right), which lie about 180 million lightyears from Earth and smashed into one another 25\u201330 million years ago. Galaxy collisions often result in a redistribution of gas and the formation of new stars, but this one created a \u2018bridge\u2019 between the two, thought to be too turbulent for star formation to occur. <\/p>\n\n
