Launched in May, ESA’s EarthCARE satellite has been making waves, with the first images from three of its scientific instruments already delivered. Now, the spotlight is firmly on the atmospheric lidar, the most advanced of the satellite’s four instruments.

Juice rerouted to Venus in world’s first lunar-Earth flyby
ESA’s Jupiter Icy Moons Explorer (Juice) has successfully completed a world-first lunar-Earth flyby, using the gravity of Earth to send it Venus-bound, on a shortcut to Jupiter through the inner Solar System.
The Wow! Signal Deciphered. It Was Hydrogen All Along.
In 1977, astronomers received a powerful, peculiar radio signal from the direction of the constellation Sagittarius. Its frequency was the same as neutral hydrogen, and astronomers had speculated that any ETIs attempting to communicate would naturally use this frequency. Now the signal, named the Wow! Signal has become lore in the SETI world.

Have astronomers found the 'secret recipe' for rapid planet growth?
Jupiter, Saturn, Neptune, and Uranus may dominate the solar system, but their formation remains mysterious. A new model could account for these planets' rapid and efficient births.
Citizen Scientists Find a Star Escaping the Milky Way
Citizen science is such a great concept. Using the combined computing power of a gazillion (exaggeration) desktop and laptops to churn through data is an excellent and efficient way of analysing volumes of data. This has been shown yet again as a star has been identified to be hurtling out to intergalactic space! Most stars in the Milky Way are not travelling fast enough to be able to escape its immense gravity but the suspected brown dwarf is travelling at 1.5 million km/h, fast enough to escape.

A Europan Lander Could Return an Ice Core For A Fraction of the Cost of Europa Clipper
Cost is a major driving factor in the development of space exploration missions. Any new technology or trick that could lower the cost of a mission makes it much more appealing for mission planners. Therefore, much of NASA’s research goes into those technologies that enable cheaper missions. For example, a few years ago, NASA’s Institute for Advanced Concepts (NIAC) supported a project by Michael VanWoerkom of ExoTerra Resource to develop a lander mission that could support a sample return from Europa. Let’s examine what made that mission different from other Europa mission architectures.
