When you think of a planet with rings, majestic Saturn almost definitely comes to mind. But it's not the only planet in the solar system with these breathtaking bands. So which planets in our solar system have rings? All four giant planets — Jupiter, Saturn, Uranus and Neptune — sport these spectacular structures. Plus, many other objects in the solar system, including the dwarf planet and asteroid Chariklo, have rings.

Weather on Earth can be wild, but it's not the only kind of weather we have to deal with. Space weather — all the winds and particles streaming off the sun — can have major impacts on Earth and human infrastructure. In the worst cases, this can mean dangerous disruption to our power grids and communications satellites. To help us predict these space storms, astronomers have a newly improved space weatherman — and it's the best one to date. The Daniel K.

Ammonia (NH3) is a common chemical here on Earth. It’s in fertiliser, refrigerator coolant and even some biological waste – if you’ve ever cleaned a fish tank, you’re surely familiar with the molecule’s scent. It’s also common beyond our planet, as its component elements of nitrogen and hydrogen are both readily produced in stars. Astronomers first spotted ammonia floating in the spaces between stars around 1970.

광활한 우주로 향하는 탐험은 나침반처럼 목적지를 가리키는 직선 항로와는 거리가 멀다. 복잡하게 얽힌 궤도 역학 속에서, 우주 탐사선은 행성 간 중력의 '당구공'처럼 튕겨 다니며, 롤러코스터 궤적을 그리듯 목적지로 향한다. 이 과정에서 핵심적인 역할을 하는 기술이 바로 '중력 지원(gravity assist)'이다. 탐사선은 거대한 행성의 중력을 이용해 속도를 높이고 궤도를 수정, 먼 우주를 향한 여정을 가속화한다. 하지만 이러한 궤도 수정은 단순한 경유 그 이상의 의미를 지닌다. 이는 탐사선의 주 임무 수행에 앞서 희귀한 표본을 수확하는 절호의 기회로, 1970년대 초기 탐사선부터 최근 베피콜롬보 수성 탐사, 그리고 곧 예정된 유로파 클리퍼 화성 탐사에 이르기까지, 수많은 태양계 탐사 미션들이 행성 '스쳐 지나가는' 찰나의 순간을 통해 괄목할 만한 과학적 성과를 거둬왔다. 특히 지구와 가까운 화성, 금성, 지구는 '근접 통과'의 주요 무대로 꼽힌다.
