Night Sky: What's in the sky this week and Helios display

Helios is the brainchild of artist Luke Jerram with his intriguing seven-metre representation of the Sun being placed on display on the South Lawn at Dyffryn Gardens from Friday, May 23 to Monday, May 26 and again from Thursday, May 29 to Sunday, June 1.
Helios, from the ancient Greek God who personifies the Sun, is on a nationwide tour and this is the Sun's only stop in Wales before moving on.
Jerram has afforded incredible attention to detail so that each centimetre of the sphere represents 2,000 kilometres of the Sun's surface which all told has been cleverly combined with a NASA-inspired soundscape. Lizzie Smith Jones, general manager for National Trust Cymru, said: 'We're beyond thrilled to welcome Helios to Dyffryn Gardens.'
The planet Jupiter finally slips into the evening twilight during the last week of May, meaning that it will be lost in the Sun's glare during June. However, on the evening of Wednesday, May 28, there is a lovely pairing with Jupiter positioned directly below a thin crescent Moon. Whilst we will lose Jupiter, we still have the red planet Mars in the evening sky for a good while yet.
On Friday, May 29, the Moon features again in the western sky after sunset but this time accompanied with the two brightest stars in the constellation of Gemini, the Twins. Forming a nice triangular shape, look for the Moon, then sweep upward to find Pollux to the left and Castor to the right.
Venus continues to dominate the sky before dawn, easily recognisable as the 'morning star' above the eastern horizon, with Saturn rising ahead of Venus and remaining to its right, although it will appear noticeably fainter.
Spaceflight news and the next private astronaut mission has been pushed back from its planned launch on May 29. With no celebrities in sight on this occasion, the crew of Axiom Space's Ax-4 will head to the International Space Station.
Amongst the quartet will be Peggy Whitson, who has spent more time in space than any other American or woman, a staggering 675 days.
Ironically, another private space company, SpaceX, will provide the Falcon 9 rocket that will power the four to the ISS, where they will conduct scientific experiments.
With Wales' own Spaceport at Llanbedr Airfield in Snowdonia seemingly on hold, further proof that you don't need a base on land to launch space-bound rockets as Galactic Energy, a privately owned Chinese company, successfully dispatched its Ceres-1 rocket with four satellites onboard from a ship at sea.
The International Space Station makes several appearances during the coming days, although the window for sighting the second of these is rather short. On Saturday, May 24, the ISS rises in the west at 10.04pm, setting in the southeast five minutes later. On Monday, May 26, the ISS rises in the southwest at 10.07pm, setting in the southwest one minute later.

Starwatch: the meeting of a star, the planet Mars and our moon

Following last week's conjunction between Regulus and Mars, the moon now gets in on the act. This meeting of a star, a planet and a moon takes place on 29 June. The chart shows the view looking west from London at 22:15 BST that day. Red planet Mars has moved on from its close pass of blue-white star Regulus, giving enough space for a waxing crescent moon to slip in between them. The moon will be 4.7 days old, and heading towards its first quarter (half-moon) phase. Just over 22% of its visible surface will be illuminated. From the moon, our nearest celestial neighbour, it takes the sunlight that bounces from its surface just 1.3 seconds to reach our eyes. For Mars, the fourth planet in our solar system, the light travel time from its surface is 15 minutes and 57 seconds. And for Regulus it takes light 79 years to reach us. So we see the moon as it appeared 1.3 seconds ago, Mars as it appeared 15 minutes and 57 seconds ago, and Regulus as it appeared 79 years ago. The conjunction is easily visible from the southern hemisphere too, where it will appear in the north-north-west.

SpaceX rocket being tested in Texas explodes, but no injuries reported

The company said the Starship 'experienced a major anomaly' at about 11pm while on the test stand preparing for the 10th flight test at Starbase, SpaceX's launch site at the southern tip of the US state. 'A safety clear area around the site was maintained throughout the operation and all personnel are safe and accounted for,' SpaceX said in a statement on X. It marked the latest in a series of incidents involving Starship rockets. On January 16, one of the massive rockets broke apart in what the company called a 'rapid unscheduled disassembly', sending trails of flaming debris near the Caribbean. Two months later, Space X lost contact with another Starship during a March 6 test flight as the spacecraft broke apart, with wreckage seen streaming over Florida. Following the back-to-back explosions, one of the 123-metre (403ft) Starship rockets, launched from Starbase, tumbled out of control and broke apart on March 27. SpaceX had hoped to release a series of mock satellites following lift-off, but this was halted when the door failed to open all the way. The spacecraft then began spinning and made an uncontrolled landing in the Indian Ocean. At the time, SpaceX chief executive Elon Musk called the launch 'a big improvement' from the two previous demonstrations and promised a much faster launch pace moving forward, with a Starship soaring every three to four weeks for the next three flights. SpaceX said Wednesday night's explosion posed no hazards to nearby communities. It asked people not to try to approach the site. The company said it was working with local officials to respond to the explosion.
