Darvaza gas crater, friendly robots and Hubble's birthday present: The best images in science for April

Take a look at the best images in science from the last month.

Published: April 30, 2022 at 5:00 pm

Have you ever done something and then instantly regretted it? That is probably what happened in Turkmenistan in 1971, when engineers looking for oil decided to set fire to a gas pocket. They thought that the fire would burn out after a few weeks. Now, over 50 years later, efforts are being made to finally extinguish the fire.

Spring is a time for new life, and in the case of science, new product launches and new technology, and we have plenty of that on offer.

So, while it's not quite time to break out the flip-flops, why not take a look through our gallery of the best images in science for April.

Closing the gate to hell

A view of the Darvaza gas crater also known as the Gate to Hell, which has been burning for almost half of a century, is seen on 2 April 2022. Steps are finally being takento close the crater due to negative effects on human health and environmental damage. The crater is located in Darvaza, in the middle of Karakum Desert, 270 kilometres from Turkmenistan’s capital, Ashgabat. The crater was first formed in 1971 during a Soviet gas drilling expedition.

Ta-Da!

Ai-Da, an ultra-realistic robot paints an image during a photocall in central London, on 4 April 2022. Ai-Da is the world’s first ultra-realistic robot artist, and is named after Ada Lovelace – regarded to be the first computer programmer. As a machine with artificial intelligence capabilities, her artist persona is part of the artwork, along with her drawings, performance art and collaborative paintings.

Eye see trees of green

This image, released on 13 April 2022, shows the largest antenna ever tested in ESA’s Hertz radio frequency test chamber. This transponder antenna will operate on the ground in Australia, and will communicate with the Biomass satellite mission to chart the health of all the forests on Earth. Part of ESA’s technical heart in the Netherlands, the metal-walled‘Hybrid European Radio Frequency and Antenna Test Zone’chamber is shut off from all external influences. Its internal walls are studded with radio-absorbing ‘anechoic’ foam pyramids, allowing radio-frequency testing without any distorting reflections. Photo by ESA/SJM Photography

It's in here somewhere

Thermal power

Engineers at MIT and the National Renewable Energy Laboratory have designed a heat engine with no moving parts. Their new demonstrations show that it converts heat to electricity with over 40 per cent efficiency — a performance better than that of traditional steam turbines. In this image, released on 13 April 2022, a thermophotovoltaic (TPV) cell is seen mounted on a heat sink. Photo by Felice Frankel

Crash landing

This image of Perseverance’s protective shell sitting upright on the surface of Jezero Crater, on the planet Mars, was collected from an altitude of 8 metres by NASA’s Ingenuity Mars Helicopter during its 26th flight at Mars on 19 April 2022. Engineers working on the Mars Sample Return program obtained images from an aerial perspective so that they could study the components’ performance during the rover’s entry, descent, and landing.
