The discovery of a distant Jupiter-like planet orbiting a dead star reveals what may happen in our solar system when the sun dies in about 5 billion years, according to new research. This unusual duo was discovered 6,500 light-years away, near the center of our Milky Way galaxy. The pairing is unexpected because this gas…MORE

New findings a ‘complete reversal’ in understanding why Earth became hospitable to life and its ‘twin’ didn’t

Venus may be a sweltering wasteland today, but scientists have questioned whether the planet was always so inhospitable. While previous studies suggested Venus might have once been covered in oceans, new research has found the opposite: Venus has likely never been able to support oceans. Researchers also determined that a similar story could have played…MORE

The planet is warming rapidly, resulting in historic drought, deadly floods and unusual melting events in the Arctic. It is also causing steady sea level rise, which scientists say will continue for decades. A new study from Climate Central, a nonprofit research group, shows that roughly 50 major coastal cities will need to implement “unprecedented”…MORE

Strange radio waves coming from the heart of the Milky Way stump scientists

Space experts have detected unusual radio waves coming from the center of the Milky Way galaxy. The energy signal is unlike any phenomenon studied before and could suggest a previously unknown stellar object, according to a new study. The brightness of the object varies dramatically, and the signal switches on and off apparently at random,…MORE

Scientists looked at more than 100,000 studies and found the world has a giant climate-crisis blind spot

Scientists using artificial intelligence to sift through around 100,000 climate studies were trying to put a number on how many people in the world were already experiencing the impacts of the climate crisis. Instead, they discovered something else: there is a worrying inequality in the world of climate science. Climate change studies are twice as…MORE
