• The crescent Moon meets Saturn in the evening sky.
  o
• At around the same time, the two objects will also make a close approach, technically called an appulse.
  o
• Appulse
  This meaning two bodies appear very near each other in the sky – usually the planets or the Moon – appear close to one another in the sky.
  o

• Dwarf planet Pluto is in solar conjunction with the Sun at 10:20am today.
  o
• This means Pluto lies on the far side of the solar system, directly behind the Sun from Earth’s perspective, and is completely hidden in the Sun’s glare.
  o
• About 3.38 billion miles away from Earth to Pluto.
  o
• Light travel time roughly 5 hours for the light cross that gap.
  o
• Never look at the Sun directly that the eye can be permanently damaged.

• On the evening of Thursday 22nd January, the Moon and Saturn will be visible low in the southwest sky after sunset.
  o
• On Friday 23rd January, the Moon & Saturn become visible after dusk, around 17:30pm, about 30–35° above the horizon, and setting by 21:30pm.

Algol Minima

o

• The bright variable star Beta Persei (Algol) will reach its minimum brightness at 20:10 / 8.10pm in the evening on Wednesday 21st January and will be visible from the UK.
  o
• Here’s a list of upcoming minimum brightness times for Algol – read more.
  o

• At this point, Mercury is hidden in the Sun’s glare and completely unobservable from Earth.
  o
• It’s also the moment when Mercury is farthest from Earth in its orbit, about 130 million miles (210 million km) away, hidden behind the Sun.
  o

• Recently solar activity has been raised the high level (red alert) to over 800 nT (nanotesia) and seen here in Milton Keynes today at 6.30 pm but it’s a shame the clouds eventually rolled in.

• Comet 24P/Schaumasse made its closest approach to the Sun on Thursday 8th January.
  o
• The period between Thursday 15th – Wednesday 28th January 2026, will have a less intrusive moon, improving chances to see fainter comets (best seen before dawn roughly 02:30am – 5:30am).
  o
• Binoculars are often essential – a small telescope helps for fainter objects or better detail.
  o
• It is predicted to reach maximum brightness of magnitude +10.
  o

• It wasn’t Mars, it was Antares, the red giant star in Scorpius.
  o
• Antares can easily be mistaken for Mars, the red planet, because it shines as a bright red star in the constellation Scorpius.
  o
• Binoculars
  By magnifying the view and reducing glare, binoculars make the red hue stand out more strongly.
  o
• Small telescope
  Even better — you’ll see Antares glowing with a deep orange‑red tint, contrasting beautifully against nearby stars.

• The Moon reaches apogee ~ the farthest point in its orbit from Earth.
  o
• The Moon appears slightly smaller and dimmer in the sky compared to perigee.
  o

• Zubenelgenubi is visible to the naked eye under clear, dark sky conditions and can be easily observed with binoculars.
  o
• Zubenelgenubi (Alpha Librae) is a wide double star: one component shines pale yellow, while the other appears light gray‑white.
  o
• It is located in the constellation of Libra, the Scales.

• Naked Eye Visibility
  Zubenelgenubi has an apparent magnitude of 2.75, making it a modestly bright star that is visible without optical aid, even from light-polluted areas.
  o
• Binocular View
  Using binoculars will reveal that Zubenelgenubi is a fascinating double star system, appearing as two separate points of light.
