Los astrónomos nunca habían visto nada parecido antes: el estallido de algo enorme en lo profundo del espacio. Los telescopios en la Tierra captaron la sorprendentemente brillante e inusual explosión en 2018, observándola mientras se desarrollaba a 200 millones de años luz de distancia. La explosión aumentó de brillo con rapidez e intensamente, mucho más de lo que se espera que ocurra con la explosión de una estrella normal, una supernova, antes de desaparecer.

Os astrônomos nunca tinham observado nada parecido antes: algo imensamente grande, explodindo nas profundezas do Universo. Em 2018, os telescópios terrestres captaram pela primeira vez esta explosão surpreendentemente brilhante e incomum, ao vivo, a 200 milhões de anos-luz de distância. O evento iluminou o espaço de forma brilhante e rápida, muito mais do que se esperaria da explosão normal de uma estrela, uma supernova – e desapareceu em seguida.

The United Kingdom’s high-risk research agency will fund £56.8 million (US$75 million) worth of projects in the controversial area of geoengineering — manipulating Earth’s environment to avert negative effects of climate change. The 21 projects include small-scale outdoor experiments that will attempt to thicken Arctic sea ice and to brighten clouds so that they reflect more sunlight.

The bizarre space explosions scientists can't explainPhilip Drury/ University of Sheffield(Credit: Philip Drury/ University of Sheffield)Astronomers have spotted around a dozen of these weird, rare blasts. Could they be signs of a special kind of black hole? Astronomers had never seen anything like it before – something vast, in the depths of space, went boom.

Humanity’s aspirations have long pushed the boundaries of our delicate balance with nature, from our expanding industrial might to our prowling of the seas. For the past several years, our ambitions have spread in earnest to the heavens, threatening to pollute space itself in a manner never seen before.

Another one! Years after it was first discovered, scientists are still struggling to explain a strange space explosion called "the Cow". Now consensus is shifting towards an intermediate mass black hole being the culprit. Story by me in @BBC_Future https://t.co/fCk8ClBTCd
Is the future of manufacturing in space? A host of companies are now developing ways to make things in space, including seed crystals for semiconductors. Coupled with new return capsules, we're entering a potentially exciting era. Story by me in @WIRED https://t.co/7VcEmrMozx
Exclusive: Scientists at a UK agency have announced £56.8m in funding for 21 geoengineering projects over the next five years. They include Earth cooling technologies, marine cloud brightening, and launching a sunshade into space. Story by me in Nature https://t.co/ji45fT3sym
