As we are based here in the UK all times are in BST. In this episode will be covering the coming week from 29 May to 4 June. I\u2019m Ezzy Pearson, the magazine\u2019s features editor. And I\u2019m joined on the podcast today by Paul Money, our reviews editor. Hello, Paul.<\/p>\n Paul <\/strong>Hello Ezzy. Looking forward to another week as quite a few things are happening this week, You know.<\/p>\n Ezzy <\/strong>I really. Well, why don\u2019t you crack on and tell us exactly what we\u2019ve got to look forward to this week?<\/p>\n Paul <\/strong>Well, we normally shout out about the planets in the evening sky, which are Venus<\/a> and Mars<\/a>, and we will come to them in a moment. And we ended last week session with looking at Saturn<\/a>, Neptune<\/a> and Jupiter<\/a> just emerging as well. But Jupiter isn\u2019t alone emerging into the morning twilight. Now, this is a very\u2026 It\u2019s not an easy apparition, but Mercury<\/a> creeps above the horizon for this week. It\u2019s not well-placed. It\u2019s in very bright twilight to the far left of Jupiter. But it is at Greatest Western Elongation<\/a> on 29 May. 25 degrees, but it\u2019s a very poor one because it\u2019s the angle of the ecliptic, you see Ezzy, and if it\u2019s shallow, then it doesn\u2019t rise very high above the horizon. If it\u2019s very steep, it gets a chance to climb higher into the sky before dropping back, usually giving us 4 to 5 weeks. We don\u2019t get that this time. You be lucky if you get it for a week, if that. So you do need an absolutely clear east, north eastern horizon. Uncluttered nothing in the way. So go to high ground. But you do need to be looking about half an hour before sunrise. And with the sky getting bright, it will be a challenge. But we like challenges, don\u2019t we? And don\u2019t forget, Jupiter is to the upper right of Mercury. So find Jupiter first and that give you a guide and go down an angle of about 20 to 30 degrees to the left. And you might pick up this elusive little planet. So, no, I always think it\u2019s worth trying. You know, always, always try to see these things. I have a very poor horizon, so unfortunately, my morning sky is absolutely rubbish. Mind you, evening sky isn\u2019t that good either. Well, usually if I usually have a little site just a couple of miles away, I can pop to if it really, really want to see these. So. But that\u2019s what you have to take into account. So the horizon does need to be pretty uncluttered. Now, I\u2019ve mentioned the evening sky and Venus and Mars, and yes, they are still there. They\u2019ve been there months. They\u2019ve been hanging around, you know, teasing us, that\u2019s the trouble. But the thing about this, Venus is trying to get closer to Mars and it won\u2019t actually ever see this particular apparition. On May the third 30th. Now we\u2019re back to the evening sky. We\u2019ve got Venus and Mars. And Venus is edging closer to Mars, but won\u2019t actually reach it, but on 30th venus is close to Kappa Geminorum. now Kappa Geminorum is 3.5, +3.5. You won\u2019t confuse it with Venus, which is -4.3. Now, Venus is steadily moving during the week and it forms a line with Pollux and Castor<\/a>, the two primary stars of Gemini<\/a> on 2 June. So it will make a line-up later this week. Now, on 30 May, Mars is also at aphelion. This is the furthest point of Mars from the Sun, and that is on 30th. But it is closing gradually on the Beehive Cluster and on 2 June it actually lies nestled within the cluster. Now that will make a brilliant\u2026 a) Visually it look great through a telescope. And b) this is a photographic opportunity, you\u2019ve got to get out there and get those photographs taken, send them into the Hot Shots gallery sort of thing. I\u2019m sure we\u2019ll hopefully put them up. So absolutely fantastic. So this is one of those times where you\u2019ve got Venus in the eveningsky, but you\u2019ve got Mars nestled within an open close, the Beehive Cluster<\/a>. She you can obviously imagine the bees swarming around\u2026 the angry bodies swarming around angry Mars.<\/p>\n Ezzy <\/strong>Yeah. Because it\u2019s it\u2019s not often that we highlight a planet when it\u2019s at aphelion, because usually it\u2019s like perihelion. That\u2019s when it\u2019s closest, that\u2019s when it\u2019s brightest. But aphelion, it\u2019s, you know, it\u2019s the other side of the Solar System. Why are we paying attention to that? But Mars, you can still. You\u2019ll see it. It is still close enough that it\u2019s quite bright in the night sky. And it\u2019s it is naked eye visible. So, yeah, I think this will definitely be a treat to to take a look at. And yes, definitely, if you do get those photos send them in to us over at www.skyatnightmagazine.com<\/a>. We always like to see them.<\/p>\n Paul <\/strong>Exactly. Sort of thing. I mean this is this is an opportunity to grab it. It\u2019s not often the line up occurs where the actual planet does go through a cluster so often like we had Venus not the other month something actually passed next to but didn\u2019t pass through the Pleiades<\/a>. You know, so yeah, to have our planet go through a cluster is quite some\u2026 and a bright cluster as well.<\/p>\n Ezzy <\/strong>I was thinking I don\u2019t, I don\u2019t think I\u2019ve seen a pitch. I mean I must have seen a picture of it at some point, but it\u2019s not a common one. So yeah, it\u2019s not something that we\u2019ve seen a lot of. So definitely be interested to see more of them.<\/p>\n Paul <\/strong>So I thought we have clear skies. That\u2019s always our, that.<\/p>\n Ezzy <\/strong>That is always the way.<\/p>\n Paul <\/strong>Bane of astronomer\u2019s life.<\/p>\n Ezzy <\/strong>But hopefully someone somewhere in the world will have clear skies at some point.<\/p>\n Paul <\/strong>Now, sticking with the evening sky, we go from 29 May to 31 at this stage for the Moon, because as usual, the Moon does dominate and often features. It\u2019s one of the main things that features in the podcast and on 29th. It\u2019s next to a star called Zania, which is Eta Virginis<\/a>. We also have it left of Porrima on the 30th sort of thing. And then on the 31st it\u2019s to the left of Spica. Now Spica is bright sort of thing, and the Moon will dominate it right next to it sort of thing. And I always find this is this is the beauty about, again, the moon\u2019s guiding you to this star, but the star is actually there all the time. It is easily naked eye and it\u2019s the main star of Virgo the Virgin. Now, the rest of the week it actually travels through Scorpius and then into Sagittarius for next week, 3 June, the almost full moon<\/a> \u2013 and I\u2019m literally talking about only a few hours before Full Moon. Full Moon technically occurs in the early hours of 4 June. But on the evening of the third, about I\u2019ve got it down to just about 10:30. You can see the virtually full Moon right next to the bright red star Antares<\/a>. And that\u2019s the heart of Scorpio, the scorpion. I just love those sort of just juxtapositions of this bright planet. This bright, well, bright star and the bright moon as well. You look over towards the southeast again, uncluttered horizon. You\u2019d have to wait just a few hours. Technically, the Moon on 4th set before it reaches technical full. But that\u2019s one of those circumstances sort of thing. If you\u2019re in the mid-Atlantic, you\u2019d see the full Moon at the point of full Moon just before it sets. But unfortunately where we are, it will have just set before it. So I just think it\u2019s virtually a full Moon, isn\u2019t it on the late night of 3rd. Yeah, it\u2019s close.<\/p>\n Ezzy <\/strong>It\u2019s close enough that you wouldn\u2019t be able to tell the difference unless you\u2019re really looking.<\/p>\n Paul <\/strong>Yeah. Unless you\u2019ve got a big telescope and you\u2019re looking at it, you\u2019d really struggle to see the difference. So I would think a few a day or so on the side of full, it\u2019s really hard to tell the phase. Whether he\u2019s full or whether there\u2019s a slight, you know, bit of shadow there.<\/p>\n Ezzy <\/strong>You can usually tell. But there is quite often is that kind of like is that is it slightly off full, or is there a smudge on my glasses kind of thing?<\/p>\n Paul <\/strong>More likely the \u201con my glasses\u201d actually. But meanwhile, on 4th itself, we still got Venus in the evening sky. I only mention it because it\u2019s actually at greatest Eastern elongation. This is 45 degrees elongation away from the Sun. So it\u2019s the furthest you can get at this stage, away from the Sun. After this, technically, Venus will start to draw back in towards the Sun. You wouldn\u2019t really think it for the next few weeks at all, but it will take place. And its phase is now technically less than half phase<\/a>, 50%. But it\u2019s always a bit smudgy sort of thing. It\u2019s very difficult to judge visually the exact point of the 50%. So be interesting to see if you would actually see that, whether you can notice whether it\u2019s actually 50% or not using a telescope. I always find it fascinating that the fact that Mercury and Venus, the only planets that can really show a very distinct phase, as in a half phase, where is Mars \u2013 you can get it gibbous. But Jupiter and the rest of planets near enough almost always look full. I know technically they aren\u2019t, but you need a lot of magnification to really bring that out. So, there we are then,\u00a0 sort of thing. Quite an exciting week. And we near enough started with Venus and Mars. But, you know, we only know\u2026 Because they dominate at the moment. So we\u2019ll have to look forward to next week.<\/p>\n Ezzy <\/strong>Yes, absolutely. Sounds like there\u2019s a fascinating week coming up for us. And if you want to hear more about that, week that we\u2019ve got coming up. Do be sure to subscribe to the Star Diary podcast to make sure that you never miss another episode. But thank you for going through that week with us, Paul. So in summary, we start the week with Venus and Mars. On 30th, Venus will be approaching Kappa Geminorum before, making a line with Castor and Pollux in Gemini on 2 June. Meanwhile, Mars is going to be reaching aphelion on 30 May, where it will be near the Beehive Cluster M44. However, on 2 June it will be slap bang in the middle of the Beehive cluster, so a great photo opportunity there on 2 June. On 29 to 31 May, the Moon will be moving along the bottom of Virgo past the stars Eta Virginis, Porrima and Spica. Then on 3 June, an almost full moon will be appearing near Antares in Scorpius. And finally, on 4 June, Venus will reach its greatest elongation in the evening sky. So lots of things to look forward to in the night sky. And we hope to all see you here next week. If you want to find out even more spectacular sites that will be gracing the night sky throughout the month.
