Can you buy XMR on Coinbase?

Could you please clarify if it's possible to purchase XMR on the Coinbase platform? I've been looking into investing in Monero and I'm wondering if my preferred exchange offers this option. I understand that Coinbase lists a wide range of cryptocurrencies, but I'm not sure if XMR is one of them. Could you guide me in this matter? If not, do you have any suggestions for reliable exchanges where I can buy Monero securely? Thank you for your assistance in this matter.
