In 1997, a host of ground-based and space telescopes confirmed that gamma-ray bursts – fleeting blasts of high energy radiation – are nature’s biggest explosions. The Italian-Dutch satellite BeppoSAX pin-pointed the February 28 burst, and Earth-based optical instruments were then able to spot its faint host galaxy several billion light-years from our planet. A typical gamma-ray burst radiates more energy in a few seconds than the Sun will in its entire 10 billion year lifetime. A gamma-ray burst (GRB) occurring in our own galaxy could decimate life on Earth, destroying the ozone layer, triggering climate change and drastically altering life’s cycle. However, the good news is that the likelihood of a natural disaster due to a GRB is much lower than previously thought.

ASTRONOMY PICTURE OF THE DAY: Doomed Star Eta Carinae. Image Credit: NASA, ESA, Hubble; Processing & License: Judy Schmidt. Eta Carinae may be about to explode but no one knows when. Eta Carinae’s mass – about 100 times greater than our Sun – makes it an excellent candidate for a full blown supernova. Historical records do show that about 170 years ago Eta Carinae underwent an unusual outburst that made it one of the brightest stars in the southern sky. Eta Carinae, in the Keyhole Nebula, is the only star currently thought to emit natural LASER light. Two distinct lobes of the Homunculus Nebula encompass the hot central region, while some strange radial streaks are visible in red extending toward the image right. The lobes are filled with lanes of gas and dust which absorb the blue and ultraviolet light emitted near the centre.

WORK OF ART: Studies of the Foetus in the Womb are two-coloured annotated sketches by Leonardo da Vinci made in around 1511. Da Vinci studied human embryology with the help of anatomist Marcantonio della Torre and saw the foetus within a cadaver. The studies were initially bequeathed to Francesco Melzi. In c. 1582–90 they were bought from his heirs by Pompeo Leoni, and by 1630 they belonged to Thomas Howard, 2nd Earl of Arundel. Since 1690 the studies have been housed in the Royal Collection, United Kingdom.
